I do feel there is hypocrisy when punters do owo, but chastise those who do bareback. The only difference is the degree of risk, and I feel that they're probably closer in terms of risk than we'd like to imagine.
I have heard far more tales on here of punters catching STDs from oral sex than from bareback sex. That's not to say that I think bareback is safer than owo, it likely represents the fact barebackers are fewer in number than those who do owo and also that barebackers are less likely to talk openly about it, but STDs are caught through oral sex.
I also think it's naive to assume a prostitute doesn't do bareback sex because she says she doesn't do bareback sex. A lot do it with punters, off the record. I've been directly and indirectly offered it. Prossies also tend to be promiscuous by nature and are probably fucking all sorts on a Friday night.
It's fine to avail yourselves of the risks and make a choice that feels right for you. I, myself, have started erring towards covered oral. But try to do it on real risks, rather than perceived risks, and be careful in your glass houses.
