“I Can’t Feel Him During Sex” – Is This Vaginismus, Birth Control, or Something Else?

As a gynaecologist, psychotherapist, and sexologist with over 30 years of experience, I am frequently asked a surprisingly common question in women’s health forums:

“I can feel him when he first enters, but once he’s inside and thrusting, I barely feel anything. Is something wrong with me? Is it vaginismus? Could it be the birth control pill?”

Because this question appears again and again — often across multiple online communities — it’s time to answer it properly, medically, and without shame.

If you’ve ever wondered the same thing, this article will give you clarity.

Is This Vaginismus?

Vaginismus is defined as an involuntary tightening of the pelvic floor muscles that makes penetration painful, difficult, or sometimes impossible.

Classic symptoms include:

• Burning, stinging, or sharp pain with penetration

• Feeling “closed” or blocked

• Involuntary muscle contraction

• Significant fear of penetration

• Difficulty inserting tampons or undergoing gynaecological exams

In many of the cases I’m asked about:

• Penetration is possible

• There may be mild discomfort with fingering

• There is some performance anxiety

• Emotional safety with the partner is present

• The primary concern is reduced sensation once penetration occurs

That pattern does not automatically indicate vaginismus.

However, mild pelvic floor tension combined with anxiety can sometimes influence sensation.

The Anatomy Most Women Are Never Taught

Understanding vaginal anatomy immediately removes much of the fear.

Here is what medical science shows:

• The outer third of the vagina contains the highest density of nerve endings.

• The inner two-thirds have significantly fewer sensory receptors.

• Once something passes beyond the pelvic floor muscle ring, sensation often decreases.

• The vagina is elastic and designed to stretch and adapt.

This means many women feel:

• Strong sensation during entry

• Less sensation once full penetration occurs

This is normal physiology.

A useful comparison is tampon use: insertion is noticeable, but once positioned correctly beyond the muscle ring, it is barely felt.

The same mechanical principle can apply during intercourse.

When Mechanics Play a Role

Sexual sensation is not only psychological — it is mechanical.

Sensation depends on:

• Erection firmness

• Girth (width)

• Pelvic floor muscle tone

• Level of arousal

• Lubrication

If a penis is not fully erect, loses rigidity during thrusting, or has a smaller girth relative to vaginal elasticity, there may be less stretch and friction against the vaginal walls.

Less stretch = less sensation.

This is not about blame.
It is about biomechanics.

When sufficient girth and firmness are present, most women report a sense of fullness or pressure.

Could Birth Control Pills Reduce Sensation?

Combined oral contraceptive pill can influence:

• Vaginal lubrication

• Libido

• Free testosterone levels

• Vaginal tissue sensitivity

In some women, hormonal contraception reduces androgen availability, which may decrease sexual sensitivity and arousal response.

Possible signs include:

• Reduced libido

• Vaginal dryness

• Lower arousal

• A feeling of genital “numbness”

If reduced sensation began after starting hormonal contraception, it is worth discussing alternatives with a healthcare provider.

However, birth control alone rarely causes a complete inability to feel penetration.

The Anxiety–Pelvic Floor Connection

Even when a woman feels emotionally safe with her partner, subtle performance anxiety can activate pelvic floor tension.

Common internal thoughts include:

• “Am I doing this right?”

• “Does he feel enough?”

• “Should I be feeling more?”

This mild anticipatory tension can:

• Reduce awareness of sensation

• Create subtle muscular holding

• Shift focus away from pleasure

This is not full vaginismus — but it is part of the same mind-body system.

Sexual response is deeply neurological.

Why Fingering Feels Different From Thrusting

An interesting pattern appears frequently:

• Fingering is felt clearly

• Penile thrusting feels minimal

This makes anatomical sense.

Fingers often stimulate:

• The outer third of the vagina

• More localized pressure points

• Slower, targeted movement

Thrusting, especially if repetitive and deeper, may bypass the most sensitive zone and create less varied stimulation.

This suggests that sensation pathways are intact.

When to Seek Professional Evaluation

Medical assessment is recommended if:

• Pain increases

• Penetration becomes difficult or impossible

• Fear escalates

• Tampon insertion is not possible

• There is a persistent feeling of “closure” or obstruction

Otherwise, reduced internal sensation alone is usually related to:

• Normal anatomy

• Elasticity differences

• Hormonal influence

• Mechanical mismatch

• Mild pelvic floor tension

Or a combination of these factors.

Gentle Adjustments That May Improve Sensation

Clinical suggestions often include:

• Slower penetration with pauses at the entrance

• Positions that increase friction (e.g., legs closer together)

• Avoiding excessive lubrication

• Pelvic floor awareness exercises

• Extended arousal before penetration

• Varied rhythm and depth

If entry is felt clearly, the body is capable of sensation.

The key becomes optimizing conditions.

The Bigger Truth

Many women assume that if they are not feeling strong internal stimulation, something is medically wrong.

In reality:

• Vaginal nerve distribution is limited internally

• The clitoris is the primary organ of sexual pleasure

• Internal fullness does not always equal high sensation

• Hormones influence response

• Mechanics matter

Reduced sensation during thrusting alone does not automatically mean Vaginismus.

And it does not mean a woman is broken.

It often means she has never been taught how her anatomy truly works.

Final Thoughts

When questions like this circulate repeatedly across forums, it tells us something important:

Women are still not receiving adequate sexual education about their own bodies.

Understanding anatomy, pelvic floor function, hormonal influence, and mechanical factors brings relief.

If symptoms involve pain, fear, or increasing difficulty with penetration, professional guidance is essential.

If not, reassurance and informed exploration may be all that is needed.

Knowledge replaces fear.
And clarity replaces shame.
