I'm not sure how I would react in this situation, but I'd like to think the escort in question (who has many highly-rated reviews on RM and has had an account there for two years now) would realize this is a collaboration. Most of us, I'm sure, want the escort to enjoy the time as much as we do. I know I do!! So I would hope that someone I was with would tell me if I had a "hygiene issue", and that's escort or not. If someone doesn't say anything than both parties potentially end up dissatisfied with one person being in the dark wondering WTF?.
And I guarantee, if the escort had a "hygiene issue" I would say something right away!
Sorry to Keith30309 for the crappy experience.
