Something must be wrong with me!! PLEASE help.

So I'm 16, and sort of maybe have the tiniest crush on a late 20s guy. Not going to actually do something about it. But he's super sweet and shy. Something is wrong with me, isn't there? Please do say something. I do need support. Again, I'm not going to act on it. I'm very mature and would never think of compromising someone's integrity, even though I would never be physical at all if something indeed happened I guess I admire him? Lol. Idk. Idk why I seem to like older people. Just happens. I feel like an idiot. God be willing for support. He has no idea. I'll get over it soon, I know it. Why do I do this, though?
