2 years difference

How bad is it to date someone 2 years younger than you? I’m 18 yo but the dude is 16 and it feels wrong in a way. He’s still in high school while I am in college , and just that makes me feel weird. But he’s a nice guy, he have the same humor, knows how to take a joke, it’s not impulsive, knows how to be respectful and not to cross the line (not like other people my age) and I genuinely like to be with him. We have a language barrier but that doesn’t bother him nor he makes fun of it. I honestly don’t think is that bad, I’m just scared that I’ll get judge from people ik
