There are lots of gay triads out there and even some quads. I was once in a triad (broke up due to reasons unrelated to poly), and am friends with a few other all-male triads. One even recently joined my local poly organization. So yes, it's out there.
If you guys do eventually consider going the route of a polyfidelitous triad dating, this is a good link with some of the best tips you can get: http://sexgeek.wordpress.com/2010/03...ks-for-triads/
It's rewarding but it will not be easy. You have to find a guy that wants to date, and fall in love, with both of you. And it be someone that both of you fall in love with. It's not just one big relationship but also three small ones inside of it.
