Why do guys like to tell who and how they f**ked?

to be honest, its an ego thing, and to be "macho" in front of the friends, that's it

not all guys do that tho

You shouldn't generalize. Not all guys do that.
Anyway, I never knew a girl that didn't do the same thing.

Actually, I don't. I hear women like to do this more than guys, even going into much more greater detail than a guy ever would. I don't believe women always do. I think it depends on the woman, just like your idea depends on the guy.

I tell my guy friends when I have a date, it's something to be excited about. But as for kissing and telling, or making up stuff, I don't do that. That's none of their business.

Aw, c'mon, I know you girls do it too. Part of the fun is bragging the next day.

Guys grow out of that for the most part. But it's something to be proud of like nailing the last shot in a game or something.

Its status thing to BOYS...most MEN have gown out if it.

Guys grow out of that for the most part. Its something guys have to be proud of, like when your mom takes your picture before prom, except its not as cute.
