Cock rings are available in many different shapes and sizes. There are looser fitting, for her pleasure only, types made to give a real big squeeze, large area covering ticklers with tendrils and nubs, small, more incognito styles and all manner of size variations in between.

One thing they nearly all have in common is an expandable ring to hug the penis base and/or balls so the materials used are along the lines of medical grade silicones and flesh mimicking materials that allow all size and shaped penises and penis like toys the chance to fit without slipping.

True, there are some metals ones on the market but know that those are much harder to remove and are designed for only very seasoned cock ring wearers. These metal cock rings, if worn too long, usually have to be removed in a hospital so don’t forget to check the time here and there and if you start getting numb with any type of cock ring, remove it immediately!
