I love them, and have been wearing them occasionally for years. my wife used to love seeing me and them. Nowadays, she could care less. Probably just like me seeing her in her granny panties. no thanks. One added benefit of thongs is when I am in the mood, that back strap snuggly holds in a butt plug. Always makes me horny, and I like the look of my erection in the pouch.
I first bought a set of thongs in Kohls, both for comfort and Safety. I climbs ladders, etc. and found my underwear was restricting my ability to move. My wife liked seeing my firm butt and my junk in a neat package. They actually felt more cool and comfortable to wear.
