Actually I don't use condoms, except those couple of times when my girlfriend got sick and vomited up the birth control pill shortly after taking it. With all the women before that I asked if they were on the pill (almost all are). It was a risk with the STDs though, but I never got any. I'd use condoms if I ever became available on the market again though, pretty dumb not to.
I know, I know. They could lie about the pill. I just have a way of knowing if a woman is crazy and not stick my dick in her. If I had the slightest doubt I wouldn't do it or pull out with the speed of light if I'm already in, even if I was horny as fuck.
