Yes, you can actually break your penis—and some sex positions can put you at a greater risk for penile fracture than others, according to a recent study published in the International Journal of Impotence Research.
For the study, researchers looked at 90 patients aged 18 to 66 who had fractured their penises. They found that 77 percent of those cases were sexual-trauma related, so they took a closer look at the sex positions being performed during the time of their injuries.
The most dangerous sex position? A whopping 41 percent of men fractured their penis during doggy style, followed by missionary and woman-on-top. The severity of the fracture was similar between doggy and missionary, but significantly worse when comparing doggy and woman-on-top, the study found.
Penile fractures occur when you put too much force on your erection. There are sponge-like tubes in the tissue of your penis that become rigid when filled with blood, urologist Tobias Köhler, M.D., told us last year. Those tubes don’t bend when they’re hit with lots of force, which can cause them to “break,” leading to pain, swelling, blood blockages, and if it’s bad enough, a trip to the ER.
