I very rarely see it, but occasionally. Only ever holding hands, never see kissing, and even those instances are... once every month or so? More rarely? See straight people holding hands all the time.
I once gave my boyfriend a hug (no kiss), and was subjected to a twenty-minute-plus tirade from a stranger on the train (and we're talking threatening, not just giving vent). My boyfriend didn't feel comfortable with any measure of public affection after that. That might have something to do with it.

What the Hell? I hug my friends all the time. If we meet up to see a movie or eat, we often all exchange hugs. Mind you, we're often trading playful insults and such while we do so, but I've never had anyone say anything to us.
Weirdly, the only person I know who doesn't hug anyone is a girl who seems to have personal space issues with it.
Oh, we also tend to hug when saying goodbye. And for the record, most of us are straight.
