honey it's all about biology. okay the hymen is a membrane, part of the vulva, which partially occludes the entrance of the vagina, and it stretches, or is sometimes torn, when the woman first engages in sexual intercourse. The human hymen can vary widely in thickness, shape, and flexibility. Throughout history, the presence of an intact membrane has been seen by some as physical evidence of "virginity". The presence of a hymen is a possible indication, but not a guarantee, of virginity, given that it is speculated that some degree of sexual activity may occur without rupturing the hymen and because there may exist varying definitions as to the type and extent of sexual activity that is required to terminate the state of "virginity". your hymen will be missed. and please don't do anything else if you havent done the research. its dangerous sweetie.
