I didn’t really know what to do. I was on my way to the bathroom to brush my teeth when I passed by my dad’s bedroom. I thought I heard something, so naturally, I turned my head to look toward his door. It was late and I thought maybe he might be watching TV. But as I looked, it was clear that what I was hearing was something else. I know my dad has sex and he doesn’t really make a habit of letting me know when it’s happening. He’s not shy about his body or his personal life, but this was one thing that was always somewhat opaque. I never knew when he was having sex, but sometimes I would see guys leave early in the morning.
