Never been a dude kisser. Don't think I've ever even kissed my dad on the cheek. Neither side of the family was dude-kiss-dude affectionate, and that's carried over into my real, non-family life. But I'm usually down for a hug.
It's strange, though, how hug rules vary from friend group to friend group. My friends from my hometown are almost all hug-types, so it was strange moving to a new place and entering into kind of what was at the time a No Hug Zone. They're not emotionally distant or socially reserved guys. Far from it, actually. Some of them are just flat-out criers, which I'm not used to. I have one friend who cannot drink so much as two glasses of red wine (specifically) without crying at some point in the night for at least a few minutes. Then he returns to Party Mode like nothing happened. That amazes me. It's like people who can get so wasted that they puke and then just wipe their mouths and start dancing again. If I cry or puke (both rarities for me), the night is OVER. No exceptions.
Anyway, I've been hanging around this group in various capacities for a decade at this point, and the hug politics have opened up a little. It happend when one core member of our group moved away. Now whenever he visits it's basically Hug City up in this piece and that occasionally carries over to the rest of us even when he's not around.
I just wrote kind of a lot about hugs. Nice.
