The other night my boyfriend and I had unprotected sex. He is 16 and I am 15. He was only in me for about 30 seconds. He did not ejaculate And no precum came out. In birth control or anything. When he was in me he did not pop my cherry. Before he put his penis in me it was not wet and after he put it in me is was not wet either. He has not masterbated in 2 weeks. I am supposed to start my period this week Friday.I am worried I won't start. I can't talk to my parents because they would kill me and my boyfriend. I don't know what to do will someone please help me?
