Why do many teenage and even young adult women check me out?

They stare at me for a split second and then look away multiple times, but some just stare at me intensely for a few seconds before looking away and repeating that. It usually happens when I was in university and later in college, as well as restaurants, stores, and malls. I think they do that either because they're wondering why my face is so asymmetrical, noticing I'm tall for an Oriental, and/or have some KPop/Drama fetish and think I'm Korean. This has been happening for years, but this never started until after I graduated highschool and only leaving university did the frequency increase.
