Is it weird to date someone younger as a woman?

I've been talking with this guy that I met from work 3 years ago. I knew he was younger than me. I was born in 1997 so I'm 27. I didn't know his birth year but I thought he was 25 or something. We get along and he seems mature and intelligent. He's got this young man humor when we talk, which I like because it makes me feel less old. I mean I don't think I am that old but now I checked and he's born in 2001 and we've got 4 year age gap. So he's 23 years old, even younger than my sister.

Is it weird to date him at my age? I'm more close to my 30s and he's more close to his 20's. And I really like him but now I'm worried.
