The discussion becomes even more interesting.
Strength, although it is valued by women, tends to have a higher currency value among men than women. Whereas, nurturing tends to be a higher value currency for women, but a lower one for males. Even a girl with SLAYER tatooed across her forehead will probably think a dad playing with his baby daughter to be cute.
Though, I don't think it's a homo-erotic thing. I contribute it more to cluelessness and a lack of maturity. You know the world as you know yourself, and when you are younger, even moreso. So as a guy, if you value toughness, bravado, posturing, etc. you assume females do to. If you devalue nurturing, relationships, positive communication, etc. you assume females do too. And that's where the frustration lies. Once guys figure out that females think differently and learn that what you think is real cool may turn them off, they begin the steps toward positive mating behavior.
