A hymen is a very thin tissue that is blocking the vagina at its opening which does break when you have sexual intercourse for the first time and results in bleeding. You might experience some amount of pain if having sex for the first time but that is a temporary condition that barely lasts. When the hymen breaks, there is no excessive bleeding but merely a few drops of blood that can be noticed and there is nothing to worry about as it is not a major cause of concern at all. There is a big misconception that most people have and that is that a woman strictly has to bleed after the first time that she has intercourse. Sometimes the man could even doubt a woman’s virginity based on these conditions resulting in a tensed situation between the couple. However virginnnity should not be judged based on this condition as a woman may or may not bleed when her hymen tears. On the other hand, there is a great possibility that the hymen has tore long back because it is extremely thin and any involvement in a rigorous activity like horse riding, a lot of cycling, swimming, using tampons during your periods, in the course of an exercise or even doing a split can lead to its tearing. Thus, you may or may not bleed when your hymen tears and if you think that the hymen falls out after it is broken, that is not the case. The tissue is pushed behind into the vagina which gets absorbed into the body. Also, even if you bleed after your first sexual intercourse, there is no guarantee that the bleeding is as a result of the hymen tearing. In fact it also could be the result of the tissues surrounding the vagina that get ruptured.
You should be concerned more about learning different techniques for penetration if you are having intercourse for the first time. One should remember to make it an enjoyable and memorable moment for both you and your partner and tearing or bleeding of the hymen should is the least of things that you should be worried about. You could however also use some precautions in case you are too worried about pregnancy or contracting certain sexually transmitted disease. Also remember that these do not provide a 100% safety from such conditions.
