So I am 15 and my boyfriend and I have been friends for 10 years. Our parents are very good friends well we started talking for 6 months then got together and we had never talked about it bc we were both virgins we never even thought it would happen well the other day we were at the house alone and we started kissing and it grew further and further into sex. We had it and since he was a virgin he didn't have any condoms so we did it without. Two days later we had it twice in the same day however short times. He pulled out and came on me however it wasn't a lot. It was only a little could he have pulled out late or just came very little ? If he came in me how long does it take for symptoms to kick in?
