Relationship with fabio?

so theres this boy in my school (his name is fabio, if that's not sexy, idk what is.) and hes a freshman and im a junior. i know my friends will hate me if i go out with a freshman, even though hes taller than most of the seniors. but i don't wanna go out with him, and right now i think he has a girlfriend. is there anyway i can have a strictly physical relationship (friends with benefits) with him?
