I will only talk about sex in detail with a few chosen friends. It's true, some women don't like talking below a certain level so I respect that. I have one married friend with whom I confided about my horrible situation with Mr. Can't Ejaculate. She didn't talk in detail about sex with her husband in turn which was fine. Since he's firmly in her life, I wouldn't want to know about it, anyway. But I was glad that she allowed me to vent and to the detail that I did.
In general, I am discrete but with those who do like to talk, like to use cute euphemisms. For example, a German friend was telling me about a tryst with an Austrian guy. Oh, so you got his brotchen, I asked. I then went to mention my date witha French guy and how I wouldn't mind checking out his baguette. I do like keeping sex playful.
