I’ve spent many years in weightlifting. Serious bodybuilders seem to have a slightly higher rate of homosexuality than the population as a whole. Powerlifters on the other hand seem to have lower rates. I think it relates to vanity of appearance. Powerlifters care about the weight they are moving, bodybuilders mainly care about how they are making their body look - big difference and draws homosexuals like flies.
I can tell you to never do a search on where former pro bodybuilders are, because some of them have gone the grossest route you can think of. Not recommended.
