I think men are less likely to resent other men who are muscular, and recognize that it's a product of hard work, not genetics. I've personally noticed that the more muscular I get, the more I check out other guy's muscles. I'm really straight, but come on, muscles just looked damned aesthetic and I just can't help it. At some point I also realized I'd rather go gay than be with a ham. Maybe female HAES Hams want a Ham trainer because they really believe fitness is genetic and want to see someone like themselves?
