What does a mature discussion about sex involve other than being really really vague about a person’s exploits?
You’re proving my point. Both by your need for details and you calling it an “exploit.”
Well if you’re not going to talk about it in some kind of detail then there’s no point in bringing it up because the conversation is going to be 10 seconds long. Also any type of sexual encounter (excluding rape of course) is an achievement and is something to be celebrated by both genders.
