In sex education when we were younger, the girls had a tape to watch about periods and body hair and the like; and the boys had a tape they watched about erections and wet dreams and such. After watching our own videos, we switched and watched the oppostie gender's videos. However, the teacher didn't give us any explanation about what happened to little boys; and the tape was painfully general. Following the scene of poor little Timmy having a "strange accident" in his bed and being too embarrassed to tell his parents, I thought that when boys got older, they all had trouble with peeing the bed.
