To elaborate on category 4. My points are:
1) I love sports
2) I love girls that also love sports
3) It's insanely attractive when they're not just humoring me and can actively participate in being a fan
4) I want women to maintain their identity and not have to feel like watching sports makes them "just one of the guys". IMHO, it doesn't make them one of the guys and it never should. It just makes them even more awesome as a woman.
