Sexually Transmitted Disease
Anal, oral, and vaginal sex can spread sexually transmitted diseases (STDs), many of which have no symptoms at all. If left untreated, they may result in major health problems. The causes of STDs include more than 30 bacteria, viruses, and parasites. Additionally, they can be transferred from mother to child through nursing or childbearing. Abdominal pain, urethral discharge or burning, vaginal discharge, and genital ulcers are typical symptoms.
