I could be way off, but the sentiment I get is that dommes consider themselves Sex Workers. I get this sense from some twitter accounts where they use that term for themselves.

I don't think they should try to make the correlation. Sex Workers are escorts. There is no sex in BDSM. Maybe only in rare or certain session types, but I think dommes should consider themselves more like performance artists.

You really don't want to lump yourselves in with the d sucking girls and Motel 6 renters.

Do you really want to be considered a SWer once cash goes away?
