What you feel and what the reality is are two different things. Chinese providers majorly don't offer what the Japanese providers are openly offering. Korean girls offer it for pretty cheap in the west coast. You can visit those sections here and on other websites, you will find many reviews of young Korean providers taking loads day in and out. I'd say Japanese and Korean are probably the most risk averse group for BBFS. But for some reason a lot of those Korean girls don't come to the east coast to work even though they would get more tips here.
The websites you can skim through now is just the tip of the iceberg.
It doesn't sound pleasant to say this, but basically the Japanese girls are only on BC (without PrEP) and they pretty much take loads of cum every day of the week.
Anyway, happy mongering. It's a risk everyone takes. Don't be naive, nobody bats perfect. Lol
