Not too long ago, TopBucks offered white-labels to many of their gay paysites but sadly that aspect of the program got closed.
At the moment, the only white-labels that I am aware of in the gay niche are for building your own cam, tube, VOD, and DVD sites. If you choose to go that route you may find this list of
white label sponsors of some benefit.
Personally, I would probably go with
AEBN for a gay VOD white-label, and have them customize it to match your site.
