I was in the same situation when I was your age. Granted I am only 13 now but whatever. I was with this girl but I didn't know if my parents wanted me to "date" then and I also thought I was young for it but if you really like this guy, GREAT for you. Just keep the relationship. Though if you don't like him, just tell him. Maybe on a Friday so that he has time to think it over during the weekend. Hope I helped!
