Masturbation and Erectile Function: What Men Should Know
By Dr. Z | Men’s Health Psychologist & Certified Sex Therapist
Many men come into therapy worried that they’ve somehow broken their bodies.
They’ve read posts or watched videos claiming that masturbating with a soft or semi-erect penis “trains” the body for failure—that it rewires the brain, damages blood flow, creates venous leaks, scars tissue, and leads inevitably to permanent erectile dysfunction.
The fear is real.
The distress is real.
But the story is more complex and far less catastrophic, than it’s often made out to be.
Let’s slow this down and talk about what actually affects erectile function, what doesn’t, and why so many men feel convinced that they’ve “programmed” themselves for failure.
How Erections Actually Work
An erection is a vascular and neurological event, influenced by:
Blood flow into the corpora cavernosa
Temporary restriction of blood outflow (venous occlusion)
Nervous system arousal (parasympathetic activation)
Hormones
Psychological state (stress, anxiety, focus, safety)
Yes, when the penis becomes fully erect, the expanding tissue compresses the veins, helping maintain firmness.
However, there is no credible evidence showing that masturbating with a partial erection causes veins to “learn” to stay open or directly creates venous leak. Venous leak is a diagnosable medical condition usually related to vascular health, aging, diabetes, or structural issues, not masturbation technique alone.
Where the Fear Comes From: Conditioning, Not Damage
What does matter is conditioning, but not in the way it’s often described online.
The brain is an efficiency machine. It learns patterns of arousal based on:
Repetition
Emotional state
Context
Level of relaxation vs. pressure
If masturbation routinely happens while:
Rushed
Distracted
Anxious
Highly focused on climax rather than sensation
…the nervous system may associate sexual release with tension rather than ease.
This doesn’t damage tissue.
It conditions stress into arousal.
That’s a very different and reversible process.
The Real Culprit: Anxiety and Performance Monitoring
Many men who struggle with erections aren’t lacking blood flow, they’re stuck in sympathetic nervous system activation (fight-or-flight).
Here’s the common loop:
A man notices his erection isn’t firm
He starts monitoring, checking, judging
His body tenses (including pelvic floor muscles)
Blood flow decreases because relaxation is required for erection
Anxiety increases
Erections weaken further
This is not because the body is broken.
It’s because erections require safety, not effort.
Pelvic Floor Tension: A Real Issue, Often Misunderstood
Yes, some men unconsciously clench pelvic floor muscles when worried about erection quality. Chronic tension can:
Interfere with relaxation
Contribute to discomfort
Increase premature ejaculation risk
Make arousal feel effortful
But this is a functional tension pattern, not evidence of permanent damage.
Importantly:
The pelvic floor is meant to respond, not stay clenched
Forcing erections through muscle tension often backfires
Relaxation, breathing, and nervous system regulation matter more than “pumping”
What About Tissue Damage and Scarring?
Claims that masturbation with a soft penis causes microscopic tears that lead to widespread scarring and loss of elasticity are not supported by clinical evidence in healthy men.
Fibrotic conditions (such as Peyronie’s disease) have known risk factors and clinical presentations. Routine masturbation, even vigorous, has not been shown to cause generalized erectile tissue scarring.
Fear-based messaging here often confuses rare medical conditions with normal sexual variation.
Why Men Can Often Masturbate but Struggle With Partners
This is one of the most painful experiences men report.
It’s not because the body “doesn’t know how to turn on anymore.”
It’s because partnered sex activates vulnerability, pressure, expectations, and evaluation.
Solo sex is private.
Partnered sex is relational.
Most erectile difficulties, especially in younger and otherwise healthy men are:
Reversible
Nervous-system driven
Influenced by anxiety, stress, and self-monitoring
Healing is not about stopping masturbation in fear.
It’s about:
Reducing performance pressure
Relearning relaxed arousal
Addressing anxiety and shame
Restoring trust in the body
What Actually Helps
Evidence-based approaches include:
Sex therapy focused on anxiety and arousal patterns
Pelvic floor relaxation (not strengthening by default)
Mindfulness and body awareness
Reducing compulsive checking and monitoring
Medical evaluation when appropriate
