I just asked Mike. He says he can't taste a difference on me. But he's also been with me for almost two years. So maybe he just doesn't remember. Either way, he says it's generally not offensive.
I have always found my mouth to be pretty gross. My teeth have always been yellow, and my tongue has always been coated. I brush my teeth and my tongue (I do it less now because I got discouraged after trying for years and getting nowhere... 5 minutes after I brushed, it would taste and smell the same as it did before), but it gets me nowhere. I feel like my mouth always tastes like mucus, and as someone else compared recently, it kind of tastes like butter. I have tried everything: gum, those little mint strips, mouth drops, tic tacs, toothpaste, mouthwash, whitening strips and polish... and none of it has ever worked for me. I kind of gave up. Of course, I'm not trying to win anyone new, so it's not really that important to me. *shrug*
All I try to do is make sure my breath isn't <i>so</i> offensive that you can smell it coming off of me. As far as tasting me in kisses... I gave up caring.
