Is it normal to feel passion for 1 person ever? i'm 37 and don't date.

I meet awesome guys all the time but am never attracted AT ALL to any of them. 7 years ago I met someone that I was immediately intensely infatuated with and grew to love quickly. We only knew each other in person a few months, but kept in touch on and off for several years. I have never even imagined kissing anyone else, and go years at a time without kissing anyone at all. I still think of him every day and dream of him a lot. It hurts, because I see what I'm missing out on. No one can force themselves into, or out of, love. My sexuality doesn't exist outside of my feelings for him. He loved me too and eventually named his daughter after me -- obviously it's not possible for us to be together.
