When I came up with this question (it was the first one to pop in my head because it's one I myself wonder/dream about occasionally...or a lot lol) my idea was very clear and much the same as your interpretation--in fact I didn't even think about crushes or anything like that--I was thinking first serious love, "the one who got away", first heart break ect. It's been really interesting to read what "first love" meant to different people--and their experience with it. I didn't realize there'd be such a vast contrast and range in interpretations but I'm glad there is! Really neat to read about! I have yet to answer my own question lol (I will), but I think you hit the nail on the head when you said your answer changes everyday--I think mine would to.
