I promote mostly for LFK, only because, some guys are just not good kissers. Many will try to suffocate me w their tongue, and it turns me off. Also, some just have terrible breath. So instead of saying, I ALWAYS do Dfk, I disclose only LFK. But when, your breath is minty fresh, or just fresh, and you have clean teeth, tongue etc, and you know how to arouse me w kissing.... I'm ALL in. Lol. I absolutely am ok w DFK depending on hygiene and chemistry. Sorry to be blunt here, but I guess, call me a picky kisser. Lol.
I've found that those little Listerine breath strips just before the session seem to gather some good comments. Even if you brush (AND FLOSS) really good before you head out, a little immediate freshness helps.
