Even as a man, I was approached for sex several times while out running. It was gross.
Having traveled a fair amount, I have never personally experienced behavior consistently this revolting in other countries. The behavior of Indian men was easily the most dissappointing part of my time there.
I asked a couple of the guys who approached me and I got two answers. One is that I'm about a foot taller and more muscular than the vast majority of indian men, i.e. I'm pretty hot. The other is that if they approach an Indian, he might know people in their community which would result in their family finding out they are gay.
Nothing terribly unusual or that I haven't encountered in the US, but the frequency with which it happened was really alarming.
Twice a guy drove up next to me on more quiet roads and starting asking questions about how to get around or something other general that I can't remember (in English, btw). I always tried to keep running and they just rode along next to me. The topic would quickly change to sex and then I would get angry and sprint back to a busy street and go away. A couple other times guys drive past me in cars and were more direct. It was never violent or particularly scary.

Now, I'm not one to judge, but the fact that it's important how good-looking the masseurs are indicates to me that people aren't just getting massages.
