First Year of High School Boyfriend?

It's my first year of high school now. (grade 7) I have been thinking about accepting to be somebodies girlfriend lately. I really like this guy, (he likes me too) and he may "ask me out" when school gets back. Most of the people around my area (my age) have had multiple boy/girlfriends. My parents are also quite strict but not overly! I have never had a Boyfriend before, I'm not scared at all just concerned about what people will think. When Was the first time you had a boyfriend and do you think that I am too young. Thankyou! (:
