“Penis captivus”: when you get stuck while having sex

Penis captivus” is a situation in which the man’s penis becomes stuck inside his partner’s vagina, which can happen even after plenty of foreplay, and can suddenly interrupt the fun! So why does the vagina clamp down like this, even when the woman is enjoying sex? And what can you do about penis captivus?

Penis captivus is caused by a contraction

Generally, in the case of penis captivus, the man will notice that his penis is stuck inside his partner, and the thrusting movement is no longer possible. A spasm, like a cramp, can occur in the vagina, imprisoning the penis inside. It is an involuntary muscular contraction that the woman cannot control. Don’t panic, and call a doctor, or get ready to go to the emergency room.

According to Dr. Neidhard, a professor of anatomy in the school of medicine in University Claude Bernard Lyon 1, penis captivus can be explained by a muscle spasm that starts in the anus, forming the shape of double eight between the urethra, the vagina and the anus. One of these muscle fibres starts in the pubis, goes by the sides of the vagina and around the rectum. Touching one of these three zones, around the anus, for example, can relax the muscle in question. You know what you need to do before going to the emergency room!

So penis captivus is caused by a contraction reflex in the muscles surrounding the vagina, during penetration. But why? Because of seizure? Or even a panic attack? The causes of this contraction are not yet understood, and the contractions appear to be involuntary. In any case, according to the specialists, it doesn’t pose any danger to the penis.

How to untangle yourselves, during penis captivus

Touch the rectum

According to Dr. Neidhard, you can relax the vagina by inserting a finger into the anus and pressing down, which should end the spasm, just like when you stretch your leg to get rid of a cramp in the calf or the hamstring. In exceptional cases, stress can cause these prolonged embraces. In this case, the woman needs to be given a relaxant such as valium in order to relax the muscles of the vagina, as well as touching the rectum.
