The pain sensation during the first sexual intercourse comes mainly from the rupture of the hymen. The intensity of the pain is directly related to the sensitivity of the individual to the painful stimulus. The hymen has a small number of nerve endings, and the process of first sex can cause painful symptoms by tearing the hymen. If the individual is highly sensitive to painful stimuli, they will feel intense pain, while if they are not very sensitive to pain, they may only feel mild pain. Many women are too nervous during the first sexual intercourse leading to vaginal cramps, which also enhance the painful feeling during sexual intercourse. After the first sexual intercourse, there will be a small amount of bleeding due to the accompanying tearing of the hymen. In principle, after the first sexual intercourse, do not have sex again for at least a week to facilitate the recovery of the torn hymen edge.
