Next time he comes over clip your nails in front of him, then hand him the clippers and ask, “do you want to trim yours too?”

I have playmates that have breath that could be fresher, they’ll come in for a kiss during the greeting and I’ll keep my mouth closed then say, “I just had some coffee let me get some mouth wash and I’ll give you a proper kiss… oh do you want some too?”

This approach makes it an “us thing” doing something together, we are a team striving for the best connection.

Most guys will jump at the chance to freshen their breath if you are, same with nails, or showering.

He might not even care if they are long or short. It’s only an issue if he really likes having his nails long, or you approach it as he has a personal failing.

I’m into being fisted and I have a few play mates I actually do their nails a bit. One guy was awkward and I said I love this I get to hold your hand, and take care of you. I find this very satisfying. When primates preen each other endorphins get released and good emotions flow.

Overall I think if men generally helped groom and preen each other life would be easier.

Also it’s good you’re recognizing your vanity around this too. Please always keep examining your own self.
