I've been in an LTR for about 6 years now and for a while now my gf has been on birth control. She's had an IUD for the last year or so. Anyway, I was reading The Rational Male again and his comments on birth control seem hard to argue. I trust my gf but you know how that goes. Condoms seem to me to be not worth it at the moment. The lowered sensation is staggering to the point that I feel like it's basically not worth having condomed sex.

Is there any other birth control methods I can consider? I've thought about vasectomy but since I'm only 24, I don't know if I may want to have kids at some point later in life and the reversal can be difficult.

Thanks in advance for any help you can lend me.
