Is it weird to like a guy whose 5 years older than me?

I’m 18 and met this guy at an event. Didn’t really notice him until he sent me a follow request after I got home. I stalked his profile and god he’s so my type. But he’s 23. I realize it sounds weird but imagine if I were 20 and him 25 its not bad then right? What do I even do im confused !! I haven’t felt this way about someone in ages.
