Now, being dominant and not asking but being offered is a different matter. If someone wants to give you a gift of money (or wine or a new pair of boots or gloves or whatever) then I see no problem with that at all.

To be honest, having talked to some Dommes who have wishlists on thier websites, most of them seem to do it not out of demanding money or gifts but rather as a way of making sure that they get suitable gifts when such are offered. I think too many of them have been given flowers when they would prefer chocolate or white wine when they'd prefer red or boots in the wrong size or colour and so on. I also think many men who like to give gifts to Mistresses prefer knowing in advance what to give instead of having to second guess.

There is a very subtle difference between demanding money for sexual services and being offered gifts for the same services. There is also a difference between sexual services and BDSM services in many cases - a distinction which most Pro-Dommes exploit to give them at least a small amount of protection from the law (however flimsy that may be it sometimes makes a difference). This is why most pro Dommes do advertise as offering no sexual services at all.
