This is my biggest concern about visiting an escort - could anyone name me an escort who is definitely clean?

Any escort that I have met has always been clean, they take lots of showers after all.
Incidentally, have you met any?
An occasional person has an STI.
Escorts are people.
Hence an occasional escort might have an STI.

I think it is impractical to take either someone you meet socially or an escort, to the sti clinic before having an '' encounter ''.
Practice effective safe sex, it might not be a 100% guarantee, but it will get you up around the 98th percentile, if not higher.
Other than that, I guess monasteries are crying out for celibate monks, or you could wait for the 'one', get tested and practice monogamy exclusively.
