A guy named Bill who had 10th grade PE the same period I had 9th grade PE. Most of us were lucky if we had the start of pubic hair.

Bill had thick, curly black hair on his arms, legs,crotch, butt, chest, back -- everywhere he didn't shave. The hair was so thick you couldn't see his muscles. It looked more like fur. (Good thing he was hung longer than average, or his gf never would have been able to find his cock.) He kept his head hair short, and razored out a cut line around his neck so he didn't look too freaky when he wore a crewneck t-shirt under his shirt. He was one of those guys who had to shave his beard every day since 7th grade.

The first time I saw him walking naked to the shower, I thought some adult had gotten lost. (Some of my classmates thought he was a narc, and not really 16, but I had a neighbor who'd one to school with him since 1st grade.)
