I used to be embarrassed but not any more!😡 I'm chewing peppermint gum until the second they knock, then in the trash in goes. (Confirmation so I know it's not me)
Handshake, how do you do, pull in for a friendly hug & a peck on the lips. Conversational chit chat, I'll explained my cpl of rules, then after a few minutes I'll say, "Go ahead & wash your hands & there's mouthwash for you to use as well."
He's done in the bathroom, discreet peek to see how far the level of the bottle has gone down (I make sure it's always full just for this reason).
Evidently he's used it, we kiss, there's NP, yay. Proceed.
Or, evidently he used it, we kiss, & there IS a problem bc he's disgusting & has rotten teeth.
"It is so hard to get fresh breath this time of year, don't you think?" as I take a swig & hand him another 1.
If that doesn't work & you're (or he is) invested in the kissing from a GFE POV, then he needs a toothbrush & no I'm sorry, you can't borrow mine, therefore kissing anywhere is off the table.
I repeat again & again: put it in their lap.
