Is 19F and 24M too big of an age gap?

Recently I’ve been going to a bar and met a guy. I’ve seen him twice now and genuinely we’re super into each other and hanging around each other all night. The second time I was there we kissed, he was my first kiss and he was so nice and chill about it.

I think I really like him (js like I’m not in love aha) and I don’t really notice the age gap, but is it weird?? I turn 20 soon but he’ll turn 25 eventually too (idk when though) so it’s the same.
