I'm more of a domainer than an adult webmaster, and finding a generic gay domain name is a lot better than some random made up name that gets no searches on the top search engines. You can use Google's keyword tool to help you search for domain names. It will tell you what terms get searched on google.

The problem is that many of the best gay"adult" domains are taken in pretty much all extensions, but if you have the money to buy a decent two word name I'd go that route.
