A lot of the guys I'm around do... Then again, they are immature idiots and think it's funny to joke like that. It's always just a joke in my observations.
Yeah I guess some do, but not very many? I would say that if a guy is flirting with you, chances are he's gay, bi or curious
Yeah...some of them around me do. I am one of their targets. xD They even touched each other's chest deliberately when they were dressing in PE locker room. I think they might be curious of gay relationships. Instead of flirting with girls, they wanna try something new. OR they might be gay in their real identity. (If so...xD)
I have never seen it, and I am really glad, because I would just get pissed off if a straight guy was pretending to be gay or bisexual but then get mad at me for "coming on to them."
Yes, straight guys do flirt with other guys either because they like making fun of the gay scene or gay people in general or because they have what is called "bromance", what was already mentioned. It's not uncommon to see this in my opinion.
I've seen straight guys do it...it wasn't because they found it funny or anything and I'm pretty sure they aren't gay it was more out of habit. I have one straight friend who has basically kissed almost all of his friends (myself included) and one that gets drunk and becomes extremely handsy with everyone...depends on the person really
