Uterine prolapse in women can be categorized into mild, moderate, and severe based on the symptoms. It occurs due to damage to the pelvic floor muscles, causing the uterus to descend from its original position and protrude through the vagina. Normal sexual activity does not affect the function of the pelvic floor muscles nor exacerbate the symptoms of uterine prolapse. However, in certain cases, such as severe prolapse where part of the uterus extends beyond the vaginal opening, like when the cervix is exposed outside the vagina, friction between the cervix and underwear might occur during normal walking or activities. This friction can cause small ulcers that may bleed or become infected, producing purulent discharge during sexual intercourse.
