I think the first time ever I was called the girl next door -type was like a month ago by a photographer who was stalking me, you might remember those few sets of photos. We actually talked about that one for quite a while because it's not something I ever identified myself with.
It's funny that I actually joke around with my mom all the time that I must barely be a teenager, because she herself is so youthful and energetic for her age. Like damn, she is 50+ and started a new hobby, ICEHOCKEY two years ago, crazy. So I don't think my teenage shenanigans are going to end any time soon ;)
The "girl next door type" can be interpreted many ways. I just see you as a great person, not as any "type". I don't like labels anyway. And my comment on going through the teenage years later than some? Well, the teenage years are a good thing. You explore, do what you want and what is considered outside the norm. That definitely is a good thing. Most people conform and are miserable. You are not a conformist.
So, I hope you continue your "teenage" years and do what makes you happy. Maybe someday soon, when someone thinks of the "girl next door type", it could be you they aspire to be. I think of it that way.
