As a time-honored classic, with modern improvements, the jockstrap is a type of underwear gay men love. There are several key features of jockstraps that helped cement this type of underwear as a prized favorite. The most obvious feature is its protective cup in the front. This feature supports your manhood, while also protecting it and keeping everything nice and comfy in your nether regions. Another neat feature of jockstraps is an opening in the back.
