Consider it as karmic justice: Not only does cheating on your wife fracture your relationship, it also fracture your penis. According to a study in Sexual Medicine, doctors at the University of Maryland found that men who have extramarital affairs are more likely to break their penises. Half of their penile fracture patients between 2007 and 2011 sustained penis injuries when they were having affairs.

The study’s lead author Andrew Kramer, M.D. says the reason why broken dicks are so common with these guys is due to their choice of adventurous infidelity venues. “A lot of these guys were having affairs in weird locations,” he says. Think: cars, elevators, bathroom stalls, and offices. “If you have sex in a weird location or a physically awkward situation where you don’t have total control over your penis, you might not be able to protect it from getting crushed.” Ouch.

Just a reminder for those of you unperturbed about the consequences, here's how such an unfortunate scenario can unfold: When you’re on top of her during intercourse, you can control how hard and how frequently you thrust. But when she’s on top and dictating the action, you can accidentally slip out, leaving your penis unprotected and at an angle where it can buckle if she makes an awkward landing. So you should always stabilize her pelvis with your hands to avoid getting crush when she goes down.
