I think a lot of dommes exit into the performing arts as well. Most all the burlesque performers I know were professional dommes for a while and some very famous dommes as well.

I am sure those with artistic aspirations are attracted to domination for it's mental stimulation, not to mention it's flexible schedule. So that's not a surprise.

I bailed on law school to be a full-time domme, so it doesn't ring true for me. Having said that, most people have creative desires and being a domme is very stimulating in that way. Being a domme, while a lot of work allows a woman to have one foot planted in the fetish world and another in painting, dancing, acting, writing or other artistic endeavors.
