So I flew the other day. Very early morning flight, everyone was pretty much asleep. About an hour into the flight, I look at the guy next to me and he had a massive erection. I know when you sleep, your body will naturally get an erection but it was so hot. I had to restrain myself to not reach out and touch it, but golly!! I just read a magazine, but I kept looking at his hard on. I am not sure what he was dreaming about , but it did eventually go down, then it got hard again. He woke up moments later, and I pretended I was reading a magazine. I think he was a little bit embarrassed because he crossed his legs and slept like that the rest of the flight.
