Yeah, it's pretty common among guys, to have talks about past 'conquests' and the like, especially in certain groups/situations. Obviously not all the time or with just anyone-- though some guys can be fucking annoying/obnoxious etc. about it of course. Drinking with friends is a time it can definitely come up.
Hadn't thought about it from a different perspective much before...
This is probably way more detail than needed, but it got me thinking, and trying to explain it for more of an 'outside perspective.'
Ime it seem more common among either groups of closer friends, or groups of like, near strangers. There seems to be a 'middle ground' where it isn't as 'common.' For an example of the 'near strangers' - when I spent a few months backpacking around British Columbia, Canada and there were quite a few times where the subject would come up relatively early from meeting. Especially after drinking and either 'giving up' for the night or coming back after. Happened commonly in a couple different hostel or those types of places I often used. Most often when we'd bump into each other in like the kitchen or 'community' areas when returning home drunk or something like that. Then start hanging out to like have a night cap and just shoot the shit. I swear this 'comparing notes' or whatever would come up plenty of nights, idk, like part of establishing each other's attitudes and whatnot, though some would definitely try to be more... 'braggy' about it. Kinda similar to how that type of situation will often lead to random chats with plenty of 'ball busting' and the like. The make-up of the group involved will definitely have a big influence too, but, especially with booze involved, it doesn't always take much to get it going. Like, even, if 3 of the 4 guys usually wouldn't just bring it up themselves, they may still join in once the other starts in. Being part of the group and all that.
Oh, and this even happened in a group where we had deep scientific and philosophical conversations and debates; a group I wouldn't have expected it nearly as much.
Also certainly skewed as those who may end up in that kind of situation generally won't often include as many introvert/homebody/net-types etc.
Oh and obviously this is a huge generalization so it won't apply to plenty, and I know it can apply to some women, especially in certain circumstances. And the whole 'don't kiss and tell' idea is of course embraced by plenty too- and for some even more so if talking about a current relationship or someone otherwise 'well known' among those having the conversation. Personally I've generally been of the approach that more 'serious' or recent/ongoing relationships are kinda left out for the most part, especially if it's less of a 'serious' conversation. And/or names usually changed/abbreviated/left out, but that's definitely not a courtesy that all have.
Idk, again, I know it's a wall of text, but trying to explain it, and kinda re-examining it myself. Seems like one possible form of like 'male bonding' I guess?
Oh, and I'm not saying it's 'right' or wrong or anything, just saying what sometimes happens, and some possible 'explanations' behind it.
