It was my first professional experience and it was horrible. I had a bad feeling the minute he opened the door. I wanted to turn and run. But, I didn't want to be rude.
Once bitten, twice shy. Still reluctant to try it again.
I work backstage of a professional theatre company. A few of the crew guys wear black nail polish. Reminds me of Herman Munster.
In porn, if a cis male's nails are too long, it's an instant "boner killer" for me.
