Like everyone else here is saying, don't think it's a big deal. Relationships are often just excuses for drama within your age group anyway. My sister's fifteen going on sixteen and I'm happy to see that she's pretty (although, predictably, not completely) disinterested in other people, romantically speaking. I would say that, on the whole, romance is more emotionally draining and time consuming than it's worth; and for someone who's still just figuring their life out, it really doesn't add much to the experience, in my opinion.
Myself, I had my first "official" boyfriend at thirteen. I had been messing around with people a long while before that but I don't really consider any of them proper relationships. It probably helped in this particular case that I dated way out of my age range (he was eighteen), so my partner was really relaxed and mature. It's also not something I think either of us were ever committed to making last, which helped us not take it too seriously. It was fun. :3
