We just clicked together, I think that's the best explanation how we came to be.
I first saw him in college. We were doing some field work and I got paired with him. I was very discreet about my bisexual orientation, at least that was what I was at that time. He was just my type, the twinky cute slim guy with a very nice sweet smile and smiling eyes that brightened up the already bright day.
We shared the same lame and shallow jokes and my heart swelled whenever I made him giggle. I loved hearing his soft chuckles and his cute eyes. I restrained myself and gathered all the strength that I could muster to keep me from jumping him, dominate him, bend him over and punish him for being the beautiful twink that he was.
He was straight, apparently, and in our side of the town, there was a big force of homophobia. I tried to hint to him that I was wanting to have sex with him, not beating around the bush, but we always talked about the girls and stuff guys talked about. At one time, I put my arms around his shoulder and we walked coyly. That was all that happened between us.
We separated ways after that field work and never saw each other again. I had relationships here and there, finished college, found work, and kept that part of me hidden from everybody, even myself. The memory of him faded, years passed by, and then there he was. I didn't recognize him at first, even the feeling I forgot. I had the same reaction though, which was a ping in my crotch, and a slight engorging of my cock.
