Question

The intent of a cock ring, is to restrict blood flow to the penis which can allow for a firmer, longer lasting erection. A rigid cock ring like this one needs to be sized properly to have the intended effect. The added benefit of a metal cock ring is that it looks cool.

Cock rings? They can do three things:

First, they're kind of like jewellery for a guy's privates, especially the fancier ones such as the one you're citing. Secondly, they can have vibrators or stimulating bits to make sex feel different for one or both parties. Thirdly, if sized correctly they can provide a harder and longer erection.

Thanks!
