bro relax , she is not pregnant...you know how hard to get someone pregnant? you have no idea, if the timing aint right even you come in her 1000 times she wont get pregnant.
I have been having sex without rubber with my gf without getting her pregnant.
here is the trick, first week after her period and last week prior her period you can come inside, cause the egg is not ready to be fertilized at that moment. I am 33 and counting the days work like a charm for me.
