Of course the Dom/me likes it too.
Unless she's just in it for the money as a pro. Even then, I think most pro Dommes love their work.
However, I know lots of kinky people who apparently can engage in their favorite kinks without getting overtly aroused, or feeling the need to have an orgasm. Just doing the kinky activity seems to be enough. Lots of play parties are arranged with a boundary of no fluids being ejected.
I'm not that way myself... far from it!
