I used to promote tranny stuff through galleries submitted to straight type MGPs/TGPs and it was probably the best converting niche that I promoted.
Re your question, a while back I asked a similar question to some gay webmasters and they said that the whole shemale niche was a world away from their own hardcore gay sites and they would never show tranny content on their gay sites and were quite offended when people used to say to them that they thought the two niches were pretty much the same thing.
