Never gotten pregnant.

Jessica
I've had raw sex multiple times with three different guys. No condom or birth control. One of my exs even supposedly had a low sperm count and came inside me once, nothing happend. Me and him had raw sex everytime and same with the other two guys. I never know if I'm lucky or if I just can't get pregnant. Has anyone else ever experienced this before? Also has anyone ever used a female condom? How is it? Please let me know.
