Sissies can be made to perform in so many ways. I find it more helpful to determine hard limit(s) then decide how that impacts what I feel like making one do for me.
Example: you're a dirty-sissy-whore-of-the evening, and a bit of a ditzy prude so don't want to dance on a the Pink Room stripper pole to earn enough nickels to buy a new thong to replace your current cum stained one.
Well you still need a new thong, so I'll have to figure out other services you're good at providing... I've taken pity on you, in a hot-dumb-sissy-sorty-way, and decide to help you earn your way to replace that old cum soaked crotch pouch on it's last legs. You're welcome.
You could very well be a sissy-whore-slut best used on their back, all fours, bent over, who knows? We'll have to experiment and figure that out, as a team. No shortage of Fortress Mistresses to take their turn on you and see what you're good at. You'd be gagged of course- we don't need your commentary. If you manage to mumble something about wanting your mouth filled with something other than a ball-gag, you might find a Mistress willing to oblige....
