Trichomoniasis is another type of vaginal infection. It is caused by a single-celled parasite that is usually spread through sex. In addition to causing bleeding after sex, it can also cause vaginal discharge and itching.
Another possible cause for bleeding after vaginal sex may be pelvic inflammatory disease (PID). Uterine fibroid tumors or polyps on the cervix or vaginal wall may also lead to vaginal bleeding during or after intercourse. Women with uterine polyps are known to experience vaginal bleeding after sex. 1  1. 2  2. 3  Next Page. 4  Last Page.
