Do slave rental services really exist?

Are there any f/sub who need long painfull sessions?

Any f/subs with fantasies about old barns and other out buildings?

I do not know if there is a slave rental service per se. I do know my girl friend wants to dress me feminine - (I kind of like the idea) she is Bi and I think she wants to mold me bi also - so there just may be something out there.
