I have only really been in love once, and I am married to that guy. The love I feel now is quite a bit different than when I first met him. In the beginning, it was like an incredible rush every time I saw him or spoke to him or even thought of him. It was like an incredible flood of amazing, nervous energy - but in a really good way. It was like the feeling I have after riding a roller coaster.
When I was young, it was more about the new experiences, the excitement of having someone new that was drawn to me and wanted to be with me. I was not just attracted to the person, but to the new experiences that I could have with him - the new people, places, and sensations that were now open to me. I was incredibly attracted to how he showed me that he cared for me. It wasn't in a romantic sense really. It was more of an 'I will do anything possible to be with you' kind of sense.
There was also a bit of drama involved with his parents. It felt a bit like Romeo and Juliet (but without the misunderstanding at the end. haha).
It was a long time ago, but that is what I remember.
I don't think what I felt in the beginning was love, though. I think it was more like the hook that kept me in the relationship long enough for me to develop love for him. The love I feel now is a lot harder to explain.
Now, if I were more certain about my personality this might help you more. Oh well...
