Hm. I suppose Allistair would count. He's an actor I admired in my youth who I sought out and befriended. I was attracted to him but he did think of me in that way. He was also the man who saved my life when I overdosed, and contacted my family about my entering rehab.
I don't know if I was attracted to him necessarily during all of this, but I would say him. So, a year or so. And I do mean genuine attraction, not lust.
