The first time i had sex i did not bleed. why is that so?

Not bleeding is fine: The bleeding with first sex idea is overdone. Bleeding means there were little tears. If a woman has a healthy vulva, vagina, and hymen; if she is very stretchy; if she is happy and relaxed, with lots of natural lubrication; if a guy enters at a good angle, at the right spot; if he moves gently with small motions until all is well-lubricated and stretched out; there may not be tearing or bleeding.
