You know who they are. They're not homophobic and they're OK with gay people but just nervous around them. Hence the new word: homonervous.
We've all seen them in the gym. They are the guys who after showering will keep their towel closely wrapped around them. When they get dressed they put their underwear on over the wet towel and then pull the towel out so that they never have to be naked. They've got it down to a science when undressing. They leave the shirt on and in one quick motion remove their boxers and slip on the briefs or gym shorts. Then quickly glance around to see if anyone saw it. Some day I would love to laugh out loud and point, then shout: "Oh my god! I saw it!"
The homonervous men are at work too. We have a restroom at the office with 2 urinals with the partition between them. The homonervous man will not even stand next to another guy who is standing there, they'd rather go into a stall and splatter on the toilet seat.
These guys sometimes won't even speak to you outside of the office space. They think that if they're being friendly a gay guy will think they're coming on to them. I'm not sure if it's an ego thing, like they think that everyone would be attracted to them.
Just get over yourselves guys!
