How I met my best friend

I first realized I wasn't like other boys when I was hanging out with my best friend, Robert. I think I was about six at the time. I asked him if he wanted to play house, though usually we would ride our bikes or play with action figures. He agreed, and we built a little house by stretching a tarp between the pile of logs and one of our bikes in the back yard. Then when he got inside, I told him to kiss me, because that's what husbands do with wives. He didn't want to but I made him do it anyway. That's when he lost interest and went home, but I felt a weird feeling, like I was falling in love with him. I never told anyone about that, and apparently neither did Robert.
