I have a dresser drawer full of thongs, from many different manufacturers. I also have a bunch of black Papi thongs for daily wear. I mostly wear white when home, but black for daily.
I wore briefs for many years, but switched to thongs back around 2004. I agree with what one poster said above. With briefs I would always get a wedgie. With a thong it's there purposefully. Thong holds the package better.
I work out every day, my build is athletic. So I do not look bad at all in thongs.
