I have done some escort work in the past. Muscle worship is the most popular fantasy asked for. Usually it's muscular straight guys who want to be a sub for an hour. VERY lucrative and fun!
I've met bodybuilders who just love being worshipped... but do not want sex with the other man. I NEVER cared about sex or even if I see the man's cock. I could spend a few hours just watching him flex while I pile on the praise.
