After reading Rhonda Jeans comment above I was thinking again "if you don't know it's weird, it doesn't feel weird." A few years ago I remember suddenly realizing that very few guys I see have 4 large earrings and shoulder length hair, and maybe I should feel weird? But I didn't, and still don't. I've even been to Mexico like this, if the natives thought I was odd I didn't notice. I've had earrings for over 2 decades, long hair most of my life since I was a teen, and those things are just normal now.

I imagine it's the same thing for nails, or even skirts (I know a guy who's been wearing kilts all his life, he thinks that's perfectly normal)

I did have a flight instructor ask me if I had problems with my earrings and wearing my headset. I said no, and that was that. Of course the same guy noticed I kicked my shoes off for the flight and mentioned it, I said "of course I do."
