Kissing a non-vegan after they eat meat?

So ladies I wonder what y'all do, I have a non-vegan boyfriend and he eats meat sometimes(not at all often anymore since I've been vegan(: ) BUT how do you guys feel about kissing a non-vegan right after they just had a big meal of a bunch of non-vegan things? For me it depends sometimes. If his breath smell like meat then yeah you gotta brush first but sometimes I just kiss him and get weirded out because what if it's on his lips? I dont know I might be crazy but I wondered if I'm the only one.
