You'd be surprised, Tress. I mean, yeah, you're right the majority of the time, but my favorite escort ever, and I mean ever, was not a domination type. Better than the dungeon I got tickled at, and they were good. And, she (the escort) didn't have sex with her people. Seriously.
She was a good tickler and a better lee. She would experiment as a ler. She would try all kinds of styles, and objects. She seemed to dig it. And she had nails for days.....
So, while Tress is right about the majority, don't limit yourself to just the dommes. Just like panning for gold...you gotta sift thru a fair amount of material before you find that gold. But when you do, it is so worth it.
