so i used to be with this chick and we would do it all the time........im talkin two to sometimes three times a day. That went on for about six months straight and we didnt use any protection because she told me she was on the shot. turns out the bitch lied and i broke it off with her and she never got pregnant. I thought maybe it was her then she ended up pregnant like four months later from some other dude. Then i thought it was me and the girl that i am with now and have been for about eight months whom by the way said yes when i proposed to her.....anyways we do it all the time and we dont use protection anymore for about the last six months. Still no pregnancy and we kinda want a kid. we both think we are ready but nothing is happening. What do i do to find out whether or not im sterile and where do i go to get it done?
