I am 23 years old, would it be weird for me to date 19 year old guy?

But he's very tall and muscular and I'm only 5'1 and very skinny, so it doesn't look weird or wrong. Like, anyone can hardly tell there's 5 years of age difference but once I tell them they make a disappointing face, specially my friends.

What do you guys think? Is it really that weird?

And I repeat it again, I'm really skinny and short. I look way younger than I am.
