While you won’t be able to simply place headphones on your junk and expect a bigger package, a Men’s Health article recently detailed one writer’s entertaining experience with a certain sound-wave therapy that uses high-intensity shockwaves—normally used to target localized fat tissues and kidney stones—directly to men’s members. Did your knees just jerk in order to protect your balls? Mine too.

The drug- and surgery-free procedure, commercially known as GAINSWave (or “extracorporeal shockwave therapy”), takes no longer than 20 minutes and aims to enhance men’s sex lives using shock waves, which stimulate the formation of new blood vessels and reactivate dormant ones in the genital region. The result of this little-known approach is improved blood flow, which ultimately helps men achieve and maintain more sustainable erections with increased sensitivity.

According to online testimony, the procedure is an effective alternative to treat erectile dysfunction, serving as a non-invasive and longer-lasting option to Viagra or Cialis, each of which have their own harvest of side-effects. For those not suffering from ED, the procedure boasts benefits outside of its primary function as well. It has also proven to increase a man’s libido, his size and vascularity.

With all these benefits explained to him through email, the writer who underwent the procedure, Ben Greenfield, accepted Dr. Richard Gaines’s invitation for a free trial. Greenfield then wrote about his hilarious experience with the procedure.

First, Greenfield was briefly interviewed by the doc, who asked him questions about his libido and hormones. Then, a sexy nurse with red lipstick takes him to a smaller room where he’s instructed to shed his clothing and apply a sizeable tube’s worth of numbing cream to his shaft and testicles (he included his taint for good measure). Greenfield then tossed on a hospital gown and laid down on the table as instructed, wondering why the hell he agreed to do this in the first place.

The nurse then re-entered the room and gets right to work, using a wand-like instrument on Greenfield’s penis. “The sensation was as if someone had just placed my entire genitalia between two high-fidelity speakers, then turned on Nine Inch Nails to full blast,” he wrote. At one point, Greenfield boldly decided to take a peak in order to see if he had a boner (he didn’t) but noticed his wiener was a discernible “pinkish-red hue.”

After 20 minutes, the procedure was done. Greenfield then left the office with a warning that, when the numbing cream wore off, he would feel a certain, distinguishable sensation—one that wasn’t revealed to readers until the moment it happened while he was out to dinner… with his grandmother.

After excusing himself from the table and sprinting to the washroom, Greenfield wrote, “My penis was venous. Big. Throbbing. A porn-star-esque mass of quivering tissue.” He adds that the “sensation” the receptionist spoke of would keep occurring that evening until he took matters into his own hands. Literally.

In the following month, Greenfield testifies that he did notice that his sexual appetite had increased, as had the size and vascularity of his boners. These effects remained present for about a month, to which his big veiny boners eventually returned back to their ordinary, Bruce Banner form.

While sound waves as a form of dick-related therapy may seem far-fetched, this unbiased writer explained without reservation that the results were as advertised. So maybe you should let your dick hear the sound of music for the first time. Just think of it as a spa day—self care, if you will.
