I tried to have sex for the first time and it could only go in half way and it hurt so bad. am i a virgin? why did it happen like that?

Hymen problem: It is normal to have a piece of tissue near the entrance to your vagina. You can use a mirror and examine yourself. Think of it like a bagel with a small hole. Your lover's penis was too large for you. Your OB can make a small slit in your hymen and solve your problem. Sorry that your first experience was uncomfortable. Hopefully your future ones will be much more enjoyable for you.
