Why don't guys that are in high school dislike me?

People don't even know me and I seriously do not look young at all and been mistaken to be somewhat older. But lately I've realized that guys that are in high school don't notice me as much, why is that? I'm a middle schooler but I'm homeschooled so maybe think think I'm in college? I've gotten noticed by some really cute middle schoolers and older guys but why not any of them?????
