OK, i've never really been sexually active with a guy. but, me and my boyfriend were messing around a few weeks ago and I gave him a hand job and he nutted. I got a little on my stomach and all over him so he went to the bathroom to clean up. He claims he washed his hands but then he came back in and fingered me. I am late on my period and I was wondering if this had anything to do with it. but then again, I started my birth control a few weeks before my start date which I'm supposed to take it the Sunday after my period.
