My finance and I have been together for nearly seven years now and been sexually active since. I cant use any birth control pills ( get very very ill when I use them ) and we're also not using any condoms ( withdrawel method ). Whats realy bothering my is that I've never fallen pregnant. I've heard that pre-ejaculation fluid also contains sperm. Could the withdrawel method realy be so effective all this time or could there perhaps be something wrong with me?
