When I was in high school, I had a slightly sexual, slightly romantic relationship with a very closeted guy who was on the football team.
He was a grade or two behind me, so not in my circle of friends, and he was definitely my first love. When I went away to college, he found someone else to carry on the hidden affair with.
All the while he had a girlfriend, played football and baseball, and no one would have ever guessed that he liked boys. I think about him once in a while.
