Hmm this has turned into a really interesting thread.
I can only speak for myself really. I have experienced love, and I've probably experienced a lot more in such a short space of time than a lot of people would do in their lifetime. I don't want to discuss that, because my friends visit this forum and I don't particularly want to share those things on the internet. So in that respect, I know it is possible for a teenager to be experienced in different situations, it isn't just about how long you've been on the planet, it's how many experiences you have been through and managed well.
Anyway I think I have had enough relationships to last me a lifetime
Haha.
I think that if you are unsure about being in love then you probably aren't in love. I don't know how to describe it, but I feel when you know, you know, there is rarely uncertainty about it.
