Premium Cock Rings

A cock ring is a ring that can be placed around a penis, usually at the base, primarily to slow the flow of blood from the erect penile tissue, thus maintaining an erection for a much longer period of time.  Cock rings can be worn around just the penis or both the penis and scrotum, or just the scrotum alone, though this is usually called a testicle cuff. 

Pleasure  - Will they increase pleasure?   With all of that bloodflow, most men experience an increase in sensitivity throughout the penis.  Wearing a cock-ring increases the sensitivity quite a bit.

Stamina - Assisting the penis in retaining its increased blood volume will definitely help with stamina and "staying power" in some men.  

Safety  -As with any sex toy or device, cock-rings are safe if used properly.  But no matter if you're using an appropriate sized ring in a safe and proper manner, you must not wear a cock-ring any longer than 30 minutes.
