I would go with guysgocrazy.com as well. GaysGoCrazy is exactly the kind of use that I was warning against. It sounds derogatory. You'll offend a good portion of your gay audience.

I think GuysGoCrazy is good because everyone already knows what to expect based on the Girls Gone Wild series. Surfers will be expecting to see guys flashing their cocks and bums etc. They're not necessarily going to be expecting to see an orgy, but that's okay. Either way, I don't think you need to qualify that they're gay because straight guys aren't going to be interested in seeing other guys flashing their dicks at the camera or having sex with one another. So I think the URL already implies this is for a gay audience.

Good luck, it looks like a winner.
