For women, vaginal bleeding during/ after sex is usually small in quantity and only in few cases can hematorrhea occur. It is a common sign of gynecological disease, thus requiring further investigation. In some cases, a woman can experience vaginal bleeding during/ after sex if there is not sufficient vaginal lubrication. This kind of bleeding can be resolved if the female becomes more relaxed, if the amount of foreplay is increased, or if the couple uses a sexual lubricant.
