My boyfriend of 8 months and I have unprotected sex regularly, and I haven't gotten pregnant. We aren't trying to have a baby, it's just more that we don't believe in birth control and don't like condoms. Plus I haven't gotten pregnant so it made it more easy to blow off protection. But even a few years ago when I was in high school my long term (2years) boyfriend and I had unprotected sex many times and nothing happened. I haven't gone to the doctor since I'm still a young adult and not trying to have kids, but should I be worried that I can't get pregnant.
