My first time was awful because the only reason I did it was because my previous boyfriend had broken up with me for refusing to have sex with him (I was 14 when that happened). So I ended up losing my virginity at 15 which I wish would have been later now. He didn't really fit and it hurt extremely bad but I think if I would have just waited a while longer I could have avoided those problems.

Just make sure its something you really want. No matter what, if your heart and your mind aren't prepared for it, it wont be a good experience at all.
