My mouth gets in the way of my dick more often than not. Once a girl asked me to talk dirty to her which i dont ever, ever like to do. And I uttered "I want to fuck every hole in your body"...didn't get past the first one. Another time in Vegas I was fornicating with the nice women who trains the Dolphins at the Mirage and I was blackout drunk randomly talking during sex. I sometimes feel it eases up the tension, and I still don't know what I was talking about leading up to it and ended it with ......"but im fucking you instead." she rolled over and I asked what way to start walking.
On the bright side, I had just finshed having sex with a girl for the first time and after, she found a full potato chip in my bed and asked why it was there, and I replied "you just got Frito-Laid". She told me about a month later, after that dumbass comment, she knew I was a good guy and she wanted me around more. I had sex with her best friend about a month after.
