Penis Rings are one of the few sex toys made specifically for men. Rings are the popular version of a medical device, called a constriction ring, and while none of the penis rings available in sex shops come with clinical testing or medical promises, they can be a functional and fun part of sex play for guys. By constricting the flow of blood out of the penis, rings can change the way erections feel, how long they last, and what orgasm and ejaculation feels like. These days many men buy rings just because they like the way they look and feel.
