I’ve mentioned this in another thread. There are STIs that can culture and thrive in the throat and that is where the potential infection would occur in a woman from bbbj. I think the chances of a woman catching something from BBBJ are greater than her getting something from DATY. If the man has one of those STIs, he’ll potentially pass it right on to her. If the guy has one of those STIs in his throat they might be able to pass this on via DATY but I suspect that’s less likely.
Listerine, believe it or not, will kill those bacteria in throats. It’s in all of those bathrooms for a reason other than shit-breath. Use it.
All that said, bbbj all the way.
