Curious how only women empathize with my situation.

The qualities I wrote up there are not a checklist that I go through, they are simply a pattern I've noticed lately. Whereas a year ago I would still be attracted to girls on an emotional level, now I feel very... neutral. I neither like nor dislike attractive girls, they just are. I feel completely disinterested but not uninterested. The situation doesn't bother me because I don't expect or hope to find a real partner while in college, but it seems antithetical to how I used to feel.
