For Transsexuals it's a bit of each for me, I want to know that I'm with a woman even though I'm not - breast, feminine looks, how she walks and talks basically. Also like any escorts she has to be committed to the job and provide what we want.
Agree Benny but there aren't many that fit all that criteria unfortunately. Iya meets that list nicely.
I've found that finding one with the right attitude seems to be the hardest aspect.
