If your website says that no sex is offered during session and you abide by those rules (most clients really are not seeking sex whatsoever), then you're not a sex worker.

I get the impression that a small minority of dommes are casually throwing around this term SWer and trying to identify as part of a group. I personally think it's foolish. You are being left alone in large part. No one is coming after you. 50 Shades of Gray and Onlyfans have mainstreamed this industry. There's no need to feel marginalized or that you have to identify with escorts, many of whom simply want to make a bunch of cash fast and will happily fade off into the distance at a moment's notice.

BDSM is different. It's fantasy roleplay. You are professionals. Skilled tradeswomen.

SWer is not a term for you. My opinion.
