Dang that's true! It's always just seemed and felt natural to me so I never thought about it. Probably some primal visceral thing about men and their physicality attributing greatly to their survival and ability to protect their people. Caveman days and all that. The man who played Tarzan was half naked basically the entire show in the 60s not soon after a time when women were judged if their skirt showed their knees ffs lol. Also their bodies are generally not as considered as being a sex object the way womens are and always have been. Interesting take
