Haven't read through this thread.
I have intention of doing so.
Some threads on this site remind me of the hashtags on Twitspace or whatever it is the youngsters are melting their brains with.
Clear, sometimes. Couldn't really give a toss if it bothers anyone; it's not my problem. Wife is cool with it and her opinion is the only one carries any weight with me ;-)
I got no clear cut recollection of ever wearing it. But I'd be amazed to learn for a fact that it never happened in my glam rock teenage years. I definitely remember getting all Alice Cooper with the eyeliner a few times. Maybe it was the 70s or maybe it was the teenager thing. Forty years on I am a bit more restrained.
Having said that, if I should find myself wearing nail polish somehow, I can't imagine that any of my friends or family would bat an eyelid. It wouldn't be there to make me look sexy, confident or tough. I'd have no reason to flaunt it or hide it. It would just be there. I doubt anyone would be any more concerned about it than my dogs would be.
A good manicure every two weeks or so, and clear nail polish. That is how a gentleman does it.
Very closely cropped fingernails, otherwise no nail polish ever, not even clear one, so far.
