Chloe's question

I am 21 years old and when I have a relationship with my boyfriend, it is very difficult to penetrate.

The first time we tried, I was a virgin and it was impossible to get in.

It took six months to achieve penetrative sex and even the next few times it was still difficult to penetrate.

It feels like a wall when I really want it.

Is there an explanation?

Catherine Blanc's response

"It's called primary vaginismus, that is to say that sexuality starts with a big difficulty of penetration which obviously leads to worry, even though it is overwhelmed with desire. There are enough concerns for, often, to position themselves badly. We therefore have two young people who are worried about hurting, for one, and having pain, for the other. Result: two clumsiness that meet and, often , two bodies which do not put in the right direction of the interlocking. Often, the young woman finds herself rather the buttocks against the bed and a little arched, which makes that her vagina goes towards the mattress when the penis is in erection.

Out of concern, the perineum can also be extremely tight.

And since it is stretched, it prevents the smooth flow of penetration.

To this is added, since there is concern, a lubrication which is not very abundant, which does not come to the point of overflowing at the level of the vulva.

However, a penis without lubrication and a vulva not yet lubricated, even if there is a desire, this prevents slipping naturally.

You shouldn't force yourself by telling yourself that it will eventually come in, right? 

This is the whole difficulty of vaginismus, it is not just a question of technical problems.

There is a little worry which causes a little awkwardness, which causes difficulties.

Otherwise, bodies are naturally made to fit together.

Since a baby with a head of ten centimeters will be able to pass, we think that anyway, the penises come in, provided, of course, that there is a favorable ground, namely this lubrication which makes all the wetness and the slightly mucus side which allows it to slide.

What can be done to improve things?

At first, trying with force will not help as there are psychological reasons for this concern. This would help fuel the idea that penetration is violence. We must therefore try to understand what is at the origin of this fear that provides this protection. Because vaginismus is above all, not an incompetence, but the expression of a protective power. "
