Yeah, I've had a few. Most even knew I was bi, and didn't care. Just guys I'm totally cool with, without anything sexual involved. We can talk about anything, hug each other, sleep practically on top of each other, tell the other you love him, cook for each other, cry in front of each other (when nobody else is around of course), and it's totally straight, like a brotherhood. It's the best friendship you can get, and we all need more of them. It's just that a lot of straight guys are too paranoid to admit that they need it.
But it's awesome when you find it.
