Instead, you’re flexing the muscles that surround the base of your penis - your pelvic floor muscles. “Skyscrapers are built to be able to sway a few inches to the right and left in case of an earthquake or high winds - the flex in your erection is similar to that.”Īs mentioned earlier, despite how it feels, you aren’t actually flexing any muscles in your penis to accomplish this. “It’s a natural evolutionary process that allows humans to use it when you want to and make your penis a little bit more mobile.” The concept, Brahmbhatt explains, is akin to the way tall buildings are built with a little bit of elasticity in case of an earthquake. “When you’re erect, your penis does have the ability to flex naturally to allow proper penetration,” says Jamin Brahmbhatt, a board-certified urologist.
