Below is a letter I wrote recently in response to thoughtful questions about resources for single Christians pursuing sexual integrity, healing from trauma, and preparation for marriage.

A Physician’s Pastoral Response on Sexual Wholeness, Healing, and Biblical Formation

Dear friend,

Thank you for writing with such honesty and care. The questions you are asking are not small ones, and the seriousness with which you are pursuing sexual wholeness, healing, and preparation for a future marriage reflects a heart that takes both Scripture and the human person seriously.

I want to honor that by giving you a substantive response — one that points you toward the best Christian resources (and some secular sources also) I know of, while also being forthright where I believe a question needs a gentle reframe rather than a straight answer.

Before I address your seven questions in turn, let me name one thing that shapes everything I will say: A biblical theology of sex does not treat sexuality as a mechanical function to be optimized, nor as an appetite to be managed in isolation.

Sexuality is covenantal. It is ordered toward self-giving love between a husband and wife, and it exists within — not apart from — our formation as whole persons who belong to Christ. That framework will be visible throughout what follows.

Some of what you are asking about is answered richly within that framework; some of it, I would suggest, rests on premises that the best Christian thinkers would gently challenge. I will try to be clear about which is which.

Finally, although I am a family physician with over four decades of practice experience, I am not professionally trained in these areas.

My responses are from the experience and heart of a Christian physician with a pastoral heart and some of the advice I’ve given patients.

However, a pastor, psychologist, researcher, or author with training and experience in these areas may well provide distinctly different advice and even have quibbles with any of the information offered below.

With that background, here are some Scriptures to ground this conversation:

• 1 Corinthians 6:12–20 — on the body as belonging to the Lord and the call to glorify God with it.
• Hebrews 4:15–16 — on drawing near to a High Priest who sympathizes with our weakness.
• Psalm 51 — on honest confession, cleansing, and the joy of restoration.
• Romans 6–8 — on union with Christ, the Spirit’s work, and the freedom of the children of God.
• Song of Solomon — for God’s good affirmation of marital affection.

Christian Ministries to Know

Here are ministries I would commend for the range of concerns you raise — recovery from pornography, single sexual integrity, sexual trauma healing, and preparation for marriage. I have grouped them so that the distinction between recovery-focused and formation-focused ministries is clear:

For Recovery, Healing, and Sexual Integrity

• Pure Desire Ministries (Dr. Ted Roberts) — Biblically grounded small-group curriculum for men and women recovering from pornography and sexual brokenness; strong on neuroscience integrated with discipleship.
• Covenant Eyes — Accountability software paired with a substantial library of free resources from Christian clinicians on recovery, shame, and healing.
• Fight the New Drug — Not explicitly Christian but science-based, widely cited by evangelical pastors; useful for the medical and psychological case against pornography.
• Harvest USA — Long-standing evangelical ministry offering discipleship resources, small groups, and counseling on sexual integrity; excellent biblical theology of sexuality.
• Regeneration Ministries — Christ-centered support for men and women navigating sexual and relational brokenness, with particular care for those healing from trauma.
• Celebrate Recovery — A widely available Christ-centered twelve-step community found in thousands of churches; very accessible entry point for ongoing accountability.
• Focus on the Family — Marriage and Relationships — Free counselor consultations, articles, and referrals; helpful for premarital formation and healing conversations.
• Restored Ministries / Mark Laaser’s legacy work (Faithful and True) — Clinical depth on sexual addiction recovery and relational trauma; Mark and Debbie Laaser’s work has shaped much of the evangelical counseling field.
• The Allender Center — Founded by Dr. Dan Allender, focused specifically on healing from sexual abuse and trauma from a richly theological perspective; professional training and lay resources.
• CCEF (Christian Counseling and Educational Foundation) — Biblical counseling resources and training; their writing on shame, desire, and sexuality is careful and pastorally rich.
• American Association of Christian Counselors (AACC) — Directory of credentialed Christian counselors, including those specializing in trauma and sexual health.
• Proven Men / Proven Women Ministries — Structured small-group curriculum for pornography recovery, with a strong emphasis on discipleship rather than willpower.

For Premarital Preparation and Marriage Enrichment

Because your questions are ultimately oriented toward a future marriage, I want to lift up a second category of ministries focused on preparation and formation as a couple. These are not recovery ministries, but they are where much of the practical work of building a healthy marital foundation takes place:

• SYMBIS (Saving Your Marriage Before It Starts) — Les and Leslie Parrott’s research-based premarital assessment and curriculum, probably the most widely used evangelical premarital tool in North America. Especially strong for couples who want a structured, data-informed conversation about compatibility, communication, and expectations.
• Prepare/Enrich — A premarital and marital inventory with more than forty years of research behind it and broad use across evangelical churches. Administered by a trained facilitator; an excellent complement to pastoral premarital counseling.
• Merge (Watermark Community Church) — Watermark’s premarital ministry, designed to prepare engaged couples through biblical teaching, mentor-couple relationships, and honest conversation about communication, finances, sexuality, and family of origin. Well-regarded and widely imitated in other churches.
• re|engage (Watermark Community Church) — A marriage-restoration ministry for couples at any stage (struggling, stable, or thriving), now replicated in hundreds of churches. Worth knowing about both for its own sake and as a model of what substantive marriage ministry can look like.
• FamilyLife’s Weekend to Remember — A weekend marriage conference that serves both premarital and married couples; the evangelical parallel to what Marriage Encounter offers, biblically grounded and accessible.
• Marriage Encounter — Worth knowing about, though with a note: the original Worldwide Marriage Encounter is Catholic in origin. Protestant expressions (including United Methodist Marriage Encounter and others) exist and follow a similar weekend format. If a reader is drawn to this kind of experience, FamilyLife’s Weekend to Remember may be the more natural evangelical fit.

Evangelical Books Worth Your Time

I have organized these by theme so they line up with your questions. I have included a few books that are not written from a Christian perspective but that many evangelical counselors recommend (I will note those). On your specific question about Wendy Maltz and others, I will address those by name in the numbered responses below.

On a biblical theology of sexuality and singleness

• Beyond the Battle by Todd Bowman — A thoughtful, clinically informed evangelical approach to sexual integrity that takes the whole person seriously.
• Finally Free by Heath Lambert — A gospel-centered, biblical counseling approach to freedom from pornography.
• Sex, Dating, and Relationships: A Fresh Approach by Gerald Hiestand and Jay Thomas — Excellent reframe of what Christian singleness and courtship look like biblically.
• The Meaning of Marriage by Timothy and Kathy Keller — The best single-volume introduction to a biblical theology of marriage, with a substantive chapter on sex.
• Redeeming Sex by Debra Hirsch — A thoughtful missional-evangelical treatment of sexuality as integral to discipleship.
• Divine Sex by Jonathan Grant — Outstanding on how modern sexual culture forms us, and how the Church forms us differently.

On preparation for married sexual intimacy

• The Gift of Sex by Clifford and Joyce Penner — Yes, I would include the Penners on your list. This remains one of the most widely recommended evangelical treatments of married sexuality, clinically informed and biblically framed.
• A Celebration of Sex by Douglas Rosenau — Also yes on your list; Rosenau is a respected Christian sex therapist and this is widely used in premarital counseling.
• Pulling Back the Shades by Dannah Gresh and Juli Slattery — Written for women but pastorally significant for anyone thinking about desire and expectation.
• Sex, Purity, and the Longings of a Girl’s Heart by Kristen Clark and Bethany Beal — A robust alternative to purity-culture shame, focused on forming desire well.
• The Great Sex Rescue by Sheila Wray Gregoire, Rebecca Gregoire Lindenbach, and Joanna Sawatsky — Evangelical authors offering a corrective to harmful teachings; their research-based approach is worth engaging, even where you may wish to test their conclusions against other evangelical voices.

On healing from sexual trauma and abuse

• The Wounded Heart by Dan Allender — The foundational evangelical text on healing from sexual abuse; indispensable.
• Healing the Wounded Heart by Dan Allender — His more recent, updated volume, incorporating decades of clinical experience.
• Mending the Soul by Steven Tracy — A theologically rich and trauma-informed resource used by many churches.
• Rid of My Disgrace by Justin and Lindsey Holcomb — Specifically for survivors of sexual assault, gospel-centered and gentle.
• The Body Keeps the Score by Bessel van der Kolk — Not Christian, but this is the standard secular text on trauma and the body; many evangelical trauma counselors cite it. Read it with theological discernment, which I will say more about below.

On healing from pornography, shame, and the renewing of the mind

• Unwanted by Jay Stringer — Outstanding. Stringer’s research-based, trauma-informed Christian approach traces unwanted sexual behavior to its roots in our story. Highly recommended for your concerns.
• Shame Interrupted by Edward Welch — A biblical counseling treatment of shame that is gospel-saturated and practical.
• The Soul of Shame by Curt Thompson — Integrates interpersonal neurobiology with Christian theology; excellent on how shame is healed in community.
• Surfing for God by Michael John Cusick — A readable, pastorally warm book on the deeper hungers beneath pornography use.
• Wired for Intimacy by William Struthers — A Christian neuroscientist’s careful treatment of what pornography does to the male brain, and how the brain can be renewed. Directly relevant to your question about images fading from memory.

Responses to Your Seven Questions

1) On building a healthy, unselfish, partner-focused sexual capacity while single.

This is a beautiful question, and it deserves a frame that the secular literature cannot quite give you. The formation of an unselfish, other-centered sexual capacity is not primarily a sexual project; it is a discipleship project. It happens as we learn self-giving love in friendship, in service, in honoring our parents, in chastity of the eyes, in forgiving those who have wronged us, in the disciplines of prayer and Scripture. 1 Corinthians 13 is the training ground for married sexuality more than any technique book.

Within that frame, the resources I would most recommend are the Penners’ The Gift of Sex, Rosenau’s A Celebration of Sex, Jonathan Grant’s Divine Sex, and Jay Stringer’s Unwanted. The Allender Center’s material on the theology of the body and longing is excellent. For the practical work of learning to see women (or men) as whole persons rather than objects — which is the heart of what you are asking — I would add Matt Fradd’s work, John Piper’s This Momentary Marriage, and the writings of the late Dr. Mark Laaser.

On Wendy Maltz specifically: she is a respected secular sex therapist whose work on healing from sexual abuse (especially The Sexual Healing Journey) is widely cited, and I will address her again under your fourth question. For your first question, however — building a premarital sexual capacity oriented toward a future spouse — her framework is not one I would recommend as a primary guide. Maltz’s underlying anthropology is broadly humanistic rather than covenantal; she treats sexual expression as a personal developmental task rather than as something that awaits and belongs to marriage. A Christian reader can glean from her work on trauma recovery (with discernment) but should not look to her for the formation of premarital sexuality.

2) On “mindful, non-compulsive masturbation without lust” as a practice for the single Christian.

I want to answer this carefully and with respect for your sincerity. You are clearly not asking in bad faith; you are trying to reason through a real question that many single Christians wrestle with. Let me say what I believe to be true, as plainly and kindly as I can.

First, on the science question you asked: no, there is no peer-reviewed medical literature that has empirically established that masturbation “without lust” is possible, let alone quantified its psychological and relational effects as distinct from masturbation with lust.

This is not because researchers have neglected the question; it is because “lust” is a theological and moral category, not a physiological one, and is therefore outside what medical research is equipped to study.

Empirical studies on masturbation (including the older Kinsey data, Masters and Johnson, and more recent work by Hyde and DeLamater and others) do not and cannot isolate a “lust-free” subset of the behavior. No Christian author — including the ones you named — has cited such a study, because it does not exist.

I would want to be honest with you about that rather than suggest otherwise.

Second, on the more important theological question: the historic and contemporary evangelical consensus, which I share, is that masturbation is not a practice to be cultivated and refined by the single believer, but rather an area where Scripture’s call is toward sexual self-stewardship that waits, prays, and pursues self-control (1 Corinthians 7, Galatians 5:22–23, 1 Thessalonians 4:3–8).

The overwhelming weight of Christian reflection — from John Stott to John Piper to the Penners to Harvest USA to Pure Desire — holds that masturbation, even in its most apparently “clean” form, turns sexual arousal inward rather than outward toward a covenant spouse, and trains the sexual appetite to be self-referential rather than self-giving.

That is the opposite of the formation you so admirably described in your first question.

That is not to pile shame on anyone who has stumbled here. There is grace, and there is real pastoral nuance among Christian thinkers (some evangelicals, like Stan and Brenna Jones in How and When to Tell Your Kids About Sex, take a somewhat more lenient view in certain narrow circumstances).

But I would not point you to “step-by-step” instructions for performing masturbation, because I do not believe such a resource — Christian or secular — would serve the formation you are trying to pursue.

The path forward is the one the first question pointed at: the slow, Spirit-empowered formation of chaste desire, not the technical refinement of a solo practice.

The best resources for this exact question are Jay Stringer’s Unwanted, Michael John Cusick’s Surfing for God, William Struthers’ Wired for Intimacy, Harvest USA’s Sexual Sanity for Men / Sexual Sanity for Women, and Heath Lambert’s Finally Free.

3) On whether sex and masturbation are biologically necessary for health or sexual functioning.

The straightforward medical answer is no — neither partnered sex nor masturbation is biologically required for general health or for the preservation of future sexual function.

No peer-reviewed longitudinal study has ever established such a requirement, because none exists to establish.

This is the consensus of reputable sexual health researchers across the field, and it is worth noting that the World Health Organization, the American Urological Association, and mainstream urologic and gynecologic texts all recognize sexual abstinence as medically benign.

Among the authors you named: Patricia Weerakoon (an Australian Christian sexologist — her Teen Sex By the Book and The Best Sex for Life are substantive), Stan and Brenna Jones (yes, especially for family and parenting frameworks), Clifford and Joyce Penner (yes), and Doug Rosenau (yes). On the secular side, Hyde and DeLamater’s Understanding Human Sexuality is a standard textbook and will give you the mainstream secular consensus, though it carries secular anthropological assumptions throughout.

A more clinically current secular reference would be the textbook edited by Irwin Goldstein and colleagues on women’s sexual function, or the work of Rosemary Basson.

What none of these authors have produced — and what does not exist — is a study proving that “decades of abstinence from both sex and masturbation carries zero health risk of any kind.”

That specific question has not been the subject of dedicated long-term cohort studies.

What we can say is this: there is no credible medical evidence that long-term chastity causes harm, and there is considerable Christian and secular testimony (from celibate clergy, single adults, widowed persons) to its livability.

That is a more honest way to frame the conclusion than appealing to a study that does not exist.

4) On healing from sexual abuse, trauma, and past violations in preparation for marriage.

Here is where I want to be especially generous, because healing is possible and hope is warranted. The single most important Christian resource in this area, apart from Scripture itself, remains Dr. Dan Allender (The Wounded Heart; Healing the Wounded Heart), along with the training and resources from The Allender Center. Steven Tracy’s Mending the Soul, Justin and Lindsey Holcomb’s Rid of My Disgrace, and Diane Langberg’s writings (On the Threshold of Hope; Suffering and the Heart of God) are all excellent.

On the authors you named:

• Wendy Maltz — Her book The Sexual Healing Journey is widely used and contains genuinely helpful practical material on reclaiming a healthy sexual self after abuse. However, Christian readers should read her with discernment, because she operates from a broadly humanistic framework and does not share a covenantal view of sexuality. With that caveat, many Christian counselors do recommend her selectively for trauma recovery work.
• Staci Haines — Her book The Survivor’s Guide to Sex is somatic and explicit; it has helped some survivors, but it carries strong secular assumptions and is not one I would place first on a Christian reading list.
• Holly Richmond — A sex therapist whose work integrates trauma and sexuality; again, helpful clinically for some, but not written from a Christian frame.
• Debby Wade — Wade is an evangelical clinician and Beyond Betrayal is a valuable resource, particularly for couples where betrayal trauma is in view.
• Bessel van der Kolk — The Body Keeps the Score is widely cited by Christian trauma counselors and represents the best of secular trauma research. His framework (that trauma is stored in the body and must be addressed somatically as well as cognitively) is genuinely illuminating and not in conflict with Christian anthropology properly understood. Read the theology elsewhere; read van der Kolk for the clinical picture.

To these I would add Aundi Kolber (Try Softer; Strong Like Water) — an evangelical trauma-informed therapist whose work is particularly accessible — and Curt Thompson (Anatomy of the Soul; The Soul of Shame), a Christian psychiatrist who integrates interpersonal neurobiology with theology.

5) On the scientific evidence that waiting for marriage is healthier than sex outside marriage.

Barbara Wilson’s The Invisible Bond is indeed one of the most accessible Christian syntheses of the neurochemistry argument (oxytocin, vasopressin, dopamine, pair-bonding) for saving sex for marriage. It is worth reading, with the caveat that the popular neurochemistry argument is sometimes presented in Christian books with more certainty than the underlying research will bear. Read it, and then read more carefully.

For deeper and more rigorous treatments, I would recommend:

• Hooked by Joe McIlhaney and Freda McKissic Bush — The Medical Institute for Sexual Health’s foundational book on the neuroscience of sexual bonding. Dr. McIlhaney is a physician and a dear friend of mine; the footnoted research base is substantial.
• Premarital Sex in America by Mark Regnerus and Jeremy Uecker — A rigorous sociological study (Oxford University Press) on the relational and life outcomes of premarital sexual behavior.
• Cheap Sex by Mark Regnerus — A follow-up; empirical sociology on contemporary sexual culture.
• Divine Sex by Jonathan Grant — While not primarily an empirical book, Grant synthesizes the social science well.
• Work by Jennifer Roback Morse (Ruth Institute) — For the sociological case for marriage and chastity.

I would gently add: the Christian case for chastity does not ultimately rest on medical studies, and we should be careful not to reduce it to a health argument.

The deeper case is covenantal, theological, and biblical. The science is corroborating evidence, not the foundation.

6) On healing from and minimizing pornographic images and sounds in memory.

The most medically credible Christian book on this is William Struthers’ Wired for Intimacy. Struthers is a neuroscientist, and the book addresses directly how pornographic content forms neural pathways and — importantly — how those pathways can be weakened, rerouted, and overwritten through the practices of abstinence, renewal of the mind (Romans 12:2), embodied worship, relational restoration, and time.

I would also recommend:

• The Brain That Changes Itself by Norman Doidge — Not a Christian book, but the most accessible popular treatment of neuroplasticity, with a chapter directly addressing pornography. This is often the most hopeful book on your specific question: the brain does change.
• Your Brain on Porn by Gary Wilson — Secular, but widely cited; Covenant Eyes and Fight the New Drug both draw on this literature.
• Closing the Window by Tim Chester — A short, practical Christian book on defeating pornography.

On the question of how soon such images and sounds substantially fade from memory: the honest answer is that it varies, and the research is not as precise as we might wish. Clinicians generally observe that intrusive recall diminishes significantly over months to a few years of genuine abstinence combined with active renewal of attention (spiritual disciplines, embodied community, trauma-informed counseling where applicable). Memories do not wholly disappear, but they lose their pull. This is consistent with both neuroscience and the lived testimony of many in recovery.

7) On healing from the shame of past pornography consumption.

This may be the most important question on your list, because shame is often what keeps people stuck long after the behavior itself has stopped. The best resources here:

• Shame Interrupted by Edward Welch — A deeply gospel-saturated biblical counseling treatment of shame. Unparalleled in its category.
• The Soul of Shame by Curt Thompson — Integrates neuroscience, attachment theory, and Christian theology. Exceptional.
• Unwanted by Jay Stringer — Traces unwanted sexual behavior back to its roots in our story, which is where shame loses its grip.
• Abba’s Child by Brennan Manning — On being loved as we are, not as we pretend.
• The Gift of Being Yourself by David Benner — A short, beautiful book on identity in Christ.
• Daring Greatly and I Thought It Was Just Me by Brené Brown — Secular, but her research on shame is foundational and frequently cited by Christian counselors. Her framework integrates well with Christian theology when the theology is supplied from elsewhere.
• From Shame to Glory (various authors; sometimes published as collections) — and the writings of Dan Allender on shame’s relationship to trauma and sexuality.

A final word

What you are doing — pursuing wholeness carefully, reading widely, asking hard questions rather than pretending the questions are not there — is itself part of the healing. It is also, quite directly, the formation for marriage that you asked about in your first question: the capacity to love a future spouse well is being shaped right now, in every season where you choose honesty over hiddenness, Scripture over slogans, and community over isolation.

Do not do this alone. Of every book and ministry on this list, the one thing I would most press on you is this: find a trusted pastor, a credentialed Christian counselor (the AACC directory is a good place to start), or a small group — Pure Desire, Harvest USA, or Celebrate Recovery — where you can be known over time. The scholarship matters. The relationships matter more.

I am grateful for your trust in asking. The Lord who began a good work in you is faithful to complete it.

With warm regard in Christ,

Walt
