I don't know if this counts, since I'd argue that in first grade I didn't have a sexual orientation at all, but nevertheless, when I was eight years old I was fascinated by how beautiful a boy in my class was. It was his skin, mostly. I've never before or since seen skin so perfectly smooth and unbroken. He also had great bone structure and a grace it seems like I must be exaggerating in my memory because no first grader could possibly be that smooth, but that's how I remember him: almost angelic.
