Most Helpful Guy
I can't honestly say that I really do that. I mean, it may occasionally come up, like, "Oh, we had somewhat of an intimate evening yesterday," if someone asks, but I never go into specifics.
I don't think it's really any of my friend's business, and it's incredibly disrespectful to whomever I happen to be dating at that time. I don't think my fiance would be too appreciative if I told all my guy friends what positions she likes, and how vocal she may or not not be during orgasm, for example.
I just have way too much respect for my partner to go around blabbing personal, intimate details about our sex life.
