Physically what happens when a girl loses her virginity?

As the other person mentioned, its different for everyone. I did not like it when I lost it, as it really did hurt. I would say 8 for the pain, and how big the guy is another thing to consider. Bleeding is because of the hymen being torn and some will bleed a lot or not.Don't do it until you are ready and lose it to the person you love, as well them caring for you. The thing about a girl becoming clingy after losing her virginity is not true, but you do feel different besides the physical aspect. You will get more respect for waiting, and a lot of guys find virgins a challenge, but once you lose it you can't take it back.
