Is it wrong for a 30+ year old man to be attracted to girls in their late teens?

[SW15]

When I turned 18 I wanted to date an 18-20 year old. As a COLLÈGE student, I wasn't going to date a High Schooler...Seriously that felt like a step down.
When I turned 21 I didn't want to date someone I couldn't go to the bar with.

I can relate to this as I felt the same way then. Over the years, I just kept wanting a 21 year old.
