I used to work abroad and OWO / CIM was almost unheard of in most places I worked.
How interesting. Is that because of sexual health or religious reasons? Whatever it is, I wouldn't disagree! Safe oral sex!
I didn't know! Did I read somewhere that in Germany, bareback will be an offence? It must be medical reasons (cross-infection control) where there are risks of potential, lifelong complications from sexually transmittable infections (herpes, cytomegalovirus, hep etc) in susceptible adults, but I stand corrected if that wasn't the case.
Sexual health. In New Zealand it's actually illegal for a sex worker to perform OWO. Or at least it was when I worked there. There were signs stipulating this in every room in the parlour I worked in. It was very, very rare anyone ever tried it on and asked for anything more. I think two or three times maximum in the whole time I was there. It never proved to be the "mood killer" "hard on killer" "feeling killer" that all the guys over here seem to like to state that it is. They never had a problem...because it was what they were used to.
The question remains to be "Is OWO safer than CIM?" If the risks are the same or almost the same.... I personally don't think punters care as so many other escorts commented on, especially "sensible ones" who know the risks and try to minimise cross-infection if they are in an LTR. Bless them.
