So.....

The first time I had sex, it was great but I guess I wasn't stretched out enough so I bled afterwards... it didn't hurt at all and at first I thought it was my period (but I knew it wasn't because I still had over a week, and because it just wasn't that kind of blood ya know?) Anyways I just wanted to hear what anyone else thought about it and any tips? I was fingered beforehand but I guess not enough?
