Introduction:

It sounds unusual as it seems unlikely for the penis to become stuck in the vagina during sexual intercourse. Penis captivus is an extremely rare condition. There are only a very few reports saying the occurrence and existence of Penis captivus. Moreover, doctors and medical professionals can identify this condition only through unscientific evidence. Those reports and evidence left many questions regarding the cause and possibilities. It is still unclear about the frequency of this condition since couples might be able to disconnect from each other before a requisition of medical care. Many couples sometimes never report such incidents to the healthcare professional because they are restorable.

What Is Penis Captivus?

Penis captivus is more of an urban myth than a fact. So, it is a rare occurrence during sexual intercourse when the vagina’s muscles restrain the penis more firmly than normal, making it harder or impossible to withdraw the penis from the vagina. This occurrence is unlikely to happen. But the most common conditions for this claim include anatomical asymmetry or the size and shape discrepancies of both the vagina and penis. Lubrication, medical conditions, and muscle spasms can also lead to penis captivus. Moreover, penis captivus is one of the manifestations of vaginismus (strict contraction of vagina muscles)

How Does Penis Captivus Occur?

A range of events is involved during sexual intercourse. During sexual arousal, the penis of a man gets filled with oxygenated blood right from the heart during an erection, and this makes the penis enlarged and erect (rigid) before orgasm or climax. In females, the walls of the vagina, composed of muscular tissue, would undergo expansion followed by contraction during sex. Also, the muscles associated with the vagina might pulse slightly at the time of orgasm. This is a normal physiological phenomenon that happens during sexual arousal and orgasm.

The muscular contractions of the vaginal walls can vary from time to time. At times, the vaginal muscles might contract stronger than usual. While these intense contractions can lead to the narrowing of the vaginal opening, preventing the man from withdrawing the penis. This atypical phenomenon happens mainly when the man is still in an engorged or erect state during the narrowing of the vaginal opening. This can eventually be solved with time. After a sex orgasm, the muscles of the vagina will tend to relax gradually. And when the man also attains orgasm, the blood in deoxygenated form begins to drain from the penis back to the heart, easing erection. Following these events, one can withdraw the penis from the vagina.

The medical reports say that most individuals who have encountered penis captivus can expect such a state for a few seconds. Hence, the couples should stay calm, letting the muscles relax for some time.

Vaginismus:

Penis captivus can also result from the vaginismus condition, and penis captivus is a significant clinical manifestation of vaginismus. Vaginismus causes involuntary spasms of the pelvic floor muscles in females. So, it is a severe contraction of the muscles of the vagina that is so rigid that the vagina closes itself. So, this spasm makes inserting tampons more difficult or impossible. This condition in women causes the inability to have intercourse. Moreover, it can also prevent certain medical screenings and exams.

How Does Penis Captivus Feel Like?

Generally, vaginal contractions might be favorable or pleasurable for males. This is because the increased pressure around the penis during an erection might amplify the sensations. Nevertheless, when the penis gets stuck within the vagina, the favorable pleasure might not be a pleasant way to reverse the concern about the quandary.

Penis captivus is unlikely to cause effects in both individuals involved in sexual intercourse. Erection is the enlargement of the penis due to increased blood flow to it. So when the erection eases, the increased pressure on the penis will drop, followed by relaxation of the associated discomforts. Simultaneously, when the contraction ceases, the muscles involved should return to a relaxed state for the vaginal opening to attain its actual size.

So, one mustn't take any measures during penis captivus since it could hurt or result in additional discomfort. Hence, one should not try to wrest oneself forcibly from the sex partner. Excess lubrication and other methods could not help with this fix. It is better to remain calm, letting the muscles relax independently. Most cases require only a few seconds and not more, though it might feel much greater.

How to Get Rid of Penis Captivus?

Penis captivus is not a profound condition to worry about. It is a rare occurrence that can be resolved with relaxation. So, if one finds that it seems less possible to disconnect from the partner during sexual intercourse, it is very important to remain calm in a stable position. One should neither panic nor forcefully withdraw, which might lead to additional pain and discomfort. So, give oneself a short break from the action. The couples can take a few deep breaths, making the muscles more likely to relax.

In case one cannot find relaxation helpful or remains in the suck position even after a short while, call for emergency medical help. The healthcare professionals might treat with muscle relaxer injections for either of a partner in helping diminution of the contractions. Also, if this condition occurs frequently, report it to the doctor immediately. The doctors will diagnose if there is any presence of underlying conditions like blood flow issues or vaginismus that are attributed to such uncommon situations.

Consequently, there are some things one can do to decrease the risk of such an occurrence.

  • Make sure that both individuals have adequate lubrication during sex.

  • The size and shape can be considered before engaging in sexual intercourse because several determinants are attributable to the challenges during sex.

  • Use effective birth control aids or condoms if one is not sexually active with their partner or has any concerns about the sexually transmitted condition status of the partner.

Conclusion:

Penis captivus is extraordinarily rare. It sounds uncommon, making it impossible to withdraw the penis from the vagina during sexual intercourse. Though it happens at rare events, it can be easily resolved within couples, even without getting much medical attention. Moreover, the effects of penis captivus are more temporary. The significant thing to consider is remaining calm and relaxed, giving it some time when it happens. This relaxation could allow the muscles to relax, making the couple disengage gradually.
