That’s why the only time a man talks about his sex life with another guy is if something extraordinary happened—usually something extraordinarily bad.
Here’s an example of something we would share. One of my friends was recently dating a woman and, after three weeks, they finally decided to get it on. It was then that she decided she had “something important” to tell him—she didn’t have a left hand. He had never noticed the missing appendage, so she felt compelled to point it out before they got naked.

For him to tell me about this might seem in poor taste, but it was something pretty extraordinary (wouldn’t you say?) that he was dying to tell someone and it’s not something you confess to a priest. I’d like to tell you more, but the guy obviously really likes her because he’s refused to hand out any more information.

While it’s one thing for a guy to talk about his own sex life, the guys who actually want to know the intimate details of another guy’s sex life are usually married.
Sad but true—some married guys want to live vicariously and get a taste of what they think they’re missing. Admittedly, the average single guy’s first instinct when he meets a guy like this is to exaggerate any such conquests to give the married guy the false impression he’s living a wild and crazy single life.
