It certainly had that effect on me. Dont get me wrong, I was never a sexual marathon man, but over the yrs, the more we talked about it, the quicker i'd cum. In the end it was like a trigger reaction. As soon as she would mention trying bbc it was all over for me. instant premature orgasm. To begin with I was ashamed of myself, then over time I came to enjoy the humiliation of it. And my wife saw it as a challenge, to see just how quick she could make me spill my seed. I got quite good at it too. lol
