Kendall, I think the very nature of a 'crush' makes that quite unlikely. To me a 'crush' means an infatuation, but implies a certain lack of a mature relationship, either through normal youthful immaturity or through unattainability.
Don't recall my first crush; there have been so many, and at my (ahem) mature point in life I still develop crushes all too often. I do remember my first love. We were fifteen; his name was Howard and I never once called him that until after we split up. I called him a diminutive from his surname. We have not exactly stayed in touch but have met from time to time, and I have met his wife (he did not marry until pretty late in life). He is a professional and when we have seen each other we have much in common still; I suspect if we had met a decade or so later we would be together still.
I also can tell you my last love. He is Paul and we have been married 29 years.
