These come in many designs. The Cock Ring tightly grips the base of the penis, retaining the blood which is producing its erection. A Cock Ring will not harden a flaccid penis, but will certainly help maintain an erection over a longer period.

For many men the use of a cock ring enhances sexual pleasure. Cock Rings can be made of metal, rubber or leather/vinyl. Metal or solid rings can be difficult to remove in a hurry, the other designs usually have a hook-and-eye or press-stud fastening. 

If you search for cock rings on the internet, you'll find a ridiculous number of different types. Some cock rings are made from rather uncomfortable materials such as leather or rigid plastic. Others require straps or use fastening devices such as snaps to secure the cock ring in place.

Other cock rings have ticklers on the end to stimulate the woman during intercourse while others, believe it or not, actually vibrate! This is for the womans benefit though really because there are very few nerve endings at the base of a mans penis.

A common question we get is "what do cock rings actually do?" You may or or may not be aware that when a man gets an errection his cock fills with blood, so in order to stop this rushing out again and to help maintain a good hard stiff cock, a man places the ring down his shaft.

A nice little side benefit, is of course, that this also makes it more difficult to ejaculate and can help prolong sex. As a result, a man who uses a cock ring will not only be larger and firmer throughout the duration of intercourse, but he will be able to last much longer than usual as well. It is of course safe and theres no reason to be afraid to try out your first cock ring. A lot of people are concerned about what happens if they ejaculate when wearing the cock ring but it does not matter, in fact its best if you do remove it though just before ejaculation as it means you will enjoy a longer, harder more forcefull and more satisfying experience.

Cock rings can be also used in conjunction with penis enlargement kits, it means you don't have to use one hand to hold the penis stiff and it actually improves the results because it provides a better and more equal amount of pressure.

The Orient was prolific in its sex aids. Perhaps the most famous of the Chinese love instruments was the silver clasp. Clamped about the base of the penis, its purpose was to prolong erection by preventing the blood from leaving the engorged organ. The Japanese "pleasure ring" has a similar purpose. Elastic bands can accomplish the same purpose.
