It is also normal for women to have no bleeding during the first intercourse for the following main reasons. First, some women are born without a hymen, so there is no rupture of the hymen during intercourse, so naturally there is no bleeding. Secondly, because the hymen is very thin, past strenuous exercise or cycling and other reasons, resulting in the hymen has ruptured, then the first time the same room will not bleed again. Thirdly, because of the adequate preparation during intercourse, the woman’s vaginal secretion is more, more lubricated, and the other party is more gentle, then even if the hymen has ruptured, it will not necessarily lead to bleeding, or bleeding is rarely not detected. Therefore, the first time intercourse does not bleed need not be too concerned.
