It seems like a small, niche market in "This" space, i.e. the Transsexual space.  I've often wondered why TER doesn't cater to the M4M or M4W market (or "Other For Other" for that matter.)  

But iIt matches my own proclivity: I lust for ultra-feminine women (or in some ways "tough" or muscular women) - totally woman other than having a nice hard dick for me (and I'm particularly fond of nice racks.)

I'd guess that the advertising venues for these sorts of providers might also include rent.men, MintBoys, and perhaps some others?

I should also think that your (OP) search might have some geographical parameters - or is it anywhere that modern transportation can get you to?

Cheers.
