Two Minutes, Tops
I hate comdoms, but I know how effective they are. For a long time, I had a girlfriend that was on the pill and we ****** all the time without putting one on. We never had a pregnancy scare (none I knew of anyway) and we didn't have to stop to wrap my **** in a piece of nearly indestructable, constricting laytex. We've broken up and it took me awhile to train myself to reach my peak with a rubber. Enter: someone else I know named Jim. He is bisexual as well and used protection for some time. Then, like me, had a girlfriend that was on the pill. He couldn't get enough of it. They'd only dated for a couple months and he was hooked on the feeling of bareback. Afterwards, he had a couple rebounds in the same week. He got herpies and HIV. After that, he just stoped caring. He's contracted just about everything now and I don't know how many girls he's gotten pregnant. The point of the story is condoms are uncomfortable and not many people like them. The same could be said about bullet-proof vests.
Don't take chances unless you're comfortable with the possible outcome.
