Hi. I've been with my boyfriend for a year and half and I'm 19 years old. Throughout our entire relationship we have not been using anyprotection. Birth control screws my stomach up, condoms hurt, so he just pulls out before he goes. After a year and a half I know their has to be a little something that has gone in. Like precum or maybe he didn't pull out fast enough. Does this mean I'm infertile or just lucky.
