I would think it is not as popular because most CDs (not all) are not exactly open about crossdressing and dont want the world (Internet) to see their faces etc. Think there is a big difference between a full blown tgirl like BAiley Jay and a crossdresser that is an amateur online. Also from what I understand most crossdresers like to dress and that is there fetish, having sex with men isnt in the cards once again not all act this way... everyone is different.
You can check out my

I would recommened for more of a Transvestite, Crossdressiing flare. But perhaps these girls might be to professional for you, not sure if you are looking for more user submitted stuff.
