...it's the same as BBFS.
Membranes is membranes. People fail to realize that. So BBBJ and BBFS--it's all membranes touching without protection.
I do BBBJCIM. Guilty as charged.
I don't offer BBFS. But there's not difference, clinically.
Don't believe me, ask my doc.
I think people just need to ask themselves how much risk they're willing to take on in this hobby. That's an individual choice. Then you choose providers/hobbyists based upon that risk factor.
And you test, test, test. Still won't keep you from getting something. Truth spoken. We are shagging virtually thousands of people, folks. For every guy I meet, I am meeting every provider he's met, and then every guy she's met...rinse, repeat, infinity.
Stay safe!
