Is it ok for a freshman girl (15) to date a junior guy (16)?

i really like this guy as a freshman, but he's a junior. I've talked about him before and all my friends say stuff like "if the grades don't touch neither do you." although i don't think it's too big of a deal - we are one year apart in age. is it really that bad?

i think i should update this and say that we're currently friends. he says he hates freshman but claims im his "favorite". maybe this helps somewhat lol
