I think POP (the TV show) was made for both genders. And why wouldn't guys watch it, I mean come on.
I would think on top of girls that POP would appeal to straight guys also just like I would think MOTU would appeal to girls.
POP = A bunch of girls in skimpy outfits (only one or two steady main good guy) together fighting evil
MOTU = A bunch of muscle guys (only two or three steady main good females) together fighting evil
Not to mention that the storyline was IMO much better. I first started watching POP when I was a kid because I had seen the SOTS movie and loved it and wanted to see more of She-ra. Plus I have always liked more female superheros than male, their stories thend to be more interesting IMO.
