So I am 16 years old and I recently lost my virginity. (i know, we shouldnt even be doing it at this age).

The second time we did it, when we started, he was dry and he went in me without a condom for about 5 seconds, but I couldnt work with it, because we were sitting up, so we stopped.  I know the chances are low but I really need some reassurance.  I have an irregular period, so I'm on the edge waiting for it to come.  I know that we shouldn't have done that, it was stupid, and he only wanted to know what it felt like for a little bit without a condom.  We are never EVER doing that again, Im going to make him use a condom every time.  Im just scared. Terrified.
