Penis captivus

Penis Captivus is a rare occurrence during sexual intercourse when the muscles in the vagina clamp down on the penis much more firmly than usual (a form of vaginismus), making it impossible for the penis to withdraw from the vagina. This is believed to happen when the muscles of the woman's pelvic floor contract and clamp down on the penis. The condition is not well documented or understood, and reports of it happening are rare.

Causes

The exact cause of penis captivus is not well understood. It is believed to be caused by a spasm of the vaginal muscles, specifically the pubococcygeus muscle. This muscle is part of the pelvic floor, and it contracts during orgasm. If the muscle spasms and contracts too much, it can trap the penis inside the vagina.

Symptoms

The main symptom of penis captivus is the inability to withdraw the penis from the vagina. This can cause panic in both partners, especially if they are unaware of the condition. Other symptoms can include pain or discomfort for both partners.

Treatment

Treatment for penis captivus is usually not necessary, as the condition typically resolves on its own once the vaginal muscles relax. In some cases, a muscle relaxant may be administered to help speed up the process. It is important for both partners to stay calm, as panic can cause the muscles to tighten even more.

Prevention

There is no known way to prevent penis captivus. It is a rare condition that is not well understood. However, understanding that it can happen and knowing what to do if it does can help reduce panic and anxiety.
