That's young nervous penis. When you're 24 and single, your penis is like the young, nervous guy in the World War II movie in the foxhole. Any sound your penis hears, it's like, 'WHAT WAS THAT?!? LET'S GO! LET'S GO LET'S GO! I'm married in my 50s. My penis is relaxed. My penis is sitting in the chair, smoking a pipe, reading the paper. My penis is like Bing Crosby. It hears a noise it's like 'I think I heard a noise, could be a hand, could be a vagina, bub bub bub.
