Why did women find him sexy?
Did you mean Elton or Mick? Elton, I think no one looked at him and found him sexy, but maybe his beautiful voice and great songs gave him a romantic appeal? Until he came out.
Mick Jagger seemed "sexy" to me as a little girl for some reason. I think because he always looked like he just had it, and was about to have it again in 5 minutes with someone else. He had a lot of charm too. Lots of confidence.
