Is having sex during menstruation harmful to a man's body?Doctor's answer:
Having sexual intercourse during menstruation, as long as the woman does not have a contagious disease, does not cause harm to the man. However, menstrual entering the male urethra may also lead to urethritis. Sexual activity during menstruation can cause significant harm to women, increasing the risk of gynecological infections.
