Should I date a younger guy?

So I like this guy he’s cute and funny and i enjoy spending time with him I’m a junior in college and he’s a freshman in college; I never really gave thought to our differences in age, but I have a younger brother his age and it kinda makes me feel weird because If i do decide to date him it like dating my younger brother (does that make sense?) anyways idk if I should go for him ? We both kind have a thing for each other but would it be weird if I date him?
