Nah the problem is not his legal age, it's his "mental age" that's creeping me out. Yeah sure, he may be 23yo but the way he thinks, acts, and does things are like a highschooler. If I were teach, I probably wouldn't be able to view him as an adult because it would feel like I'm doing something immoral. Think adults with brain development issues and have the mental capacity of a 10yo. Can you see yourself dating such an adult without feeling something's wrong?
