The hymen is a thin membrane located at the entrance of the vagina. It can be elastic and come in various shapes and sizes, so sometimes, after initial vaginal penetration, there may be a small tear and some bleeding (nothing shocking or concerning). Therefore, it is possible that even with masturbation, depending on whether it involves penetration, the hymen could tear. If the hymen is particularly rigid, even a finger could tear it, but this occurrence is rare. There are some individuals with a vagina who experience no bleeding even during their first penetrative sexual encounter because their hymen is so elastic that it undergoes no change. Therefore, it is important to understand that every hymen is different and that masturbating does not cause any long-term issues, even if a small tear may occur.
