Cock rings have been in existence for over 2000 years and were used then as they still are today. To help maintain and enhance an erection, boosting sexual pleasure and as decorative jewellery for the manhood. There are a wide number of materials used today just as there was then with rubber, leather and metal being the most popular materials used to produce modern erection rings.
There is all manner of different cock rings available with the jelly like thicker donut style ring being one of the most popular. The Perfect Fit Silaskin Cruiser Cock Ring is donut style cock ring made with a super thick and blubbery silaskin material. Even though it's quite thick, the Siliskin material is super stretchy that gently restricts the blood flow to your manhood.
These cock rings are fairly easy to get on because of the amount of stretch that they have. Just pop your manhood through the hole and then stretch it over your balls so that it sits nicely behind them close to your body. Or depending on how big you are, you could wear it just on the shaft.
Fitting Advice
As always, the fit is going to depend on your personal preference and how tight a fit you like from your cock ring. This cock ring should give the average man a nice firm fit. If you are bigger than average, then the extra stretch should help you get them on. Remember that you ideally want the inner ring to be slightly smaller than the circumference around the base of your manhood and balls.
