I have never had a provider try to be sneaky about taking the cover off. That is a MAJOR red flag. Especially for a NON-American to have an American baby. that's terrifying to be honest. However, I know plenty of guys who have done the same thing, with providers, slipping the condom off on the last second before going in. Which is also a shitty thing to do.
As far as the ads advertising it. I think most of them are hustles/or fake. Either trying to scam you, as was said earlier, or get you to arrive for service, and then a MAJOR upsell.
Then there are some girls you see advertising it and they are usually the absolute bottom of the barrel, DA's And I would take a hard pass.
With that said, there are TONS of guys who want that, and are willing to pay providers more for it. And MANY more than we think will accept it. Especially with repeat clients. Like everything else we do. The risk vs rewards re something you have to weigh out yourself, and be prepared for the consequences. I have known a lot of sugar type of girls, who aren't exactly full blown pros who go RAW on the regular. Some have asked to see test results, but most do not ask. They like it RAW just as much as we do. I get tested often, if I am practicing risky behavior. I am sure not everyone does. LOL To each their own.
