Not into it. Period. I have no online slaves and two offline girls on a sporadic base who have their own lives, families and dreams; and money is NEVER the issue.
Furthermore, I find it disgusting, and a sign of cheap-bastard-type-of-exploitation. Want to spend/lose money? Get a hooker, don't try to involve BDSM into it, where LOVE, TRUST and reciprocity are so much part of this...
Lets put it this way: NO Dom/Domme who intends to control your money as part of hi/her curriculum, would EVER pass the Acid test...
