Patient's question:
Sex with blood, and there is also pain when urinatingDoctor's answer:
There are many reasons for female coital bleeding, which can be divided into two major categories: improper coital practices and local organic lesions in the female reproductive system, with the latter being more common. For example, hymen rupture or injury can cause bleeding, usually in small amounts. However, in cases where the hymen is particularly thick and the female's actions are overly forceful, more significant bleeding may occur. Vaginal developmental abnormalities, such as a narrow or malformed vagina, can lead to vaginal bleeding if coital actions are rough, resulting in lacerations of the vaginal wall or posterior fornix. Other causes include cervical cancer, cervical polyps, cervical erosion, trichomoniasis, candidiasis, submucosal uterine fibroids, and others. Additionally, abnormal menstruation may lead to bleeding if coital intercourse occurs prematurely after menstruation has been assumed to have ended, causing uterine contractions and the expulsion of residual blood from the vagina. Furthermore, some women may experience ovulatory bleeding during their fertile period.
