it has been my experience that guys, when only around other guys, will talk about sex and women.
All depends upon your type of friends.
I've never had any who talk about these
issues very often. Though some innuendo
would occur. Normally we'd talk about gaming
and history, or just serendipity.
Always noticed that the guys who seemed
to hang around chatting about stuff like that
just had little else to talk about. The only thing
that really would bore the shit out of me, with
the group that I hung out with, was that they'd
talk about football a lot.
This was even the case in HS. Ah, we were a bit
more obsessed with sex, but almost never talked
about it.
