The Sarge series includes stainless steel luxury cock rings made of nickelfree metal. A cock ring promotes a longlasting and hard erection and looks sexy too! You'll wear this cock ring around both the penis and scrotum: slide the ring around a semierect penis and use a little lubricant if necessary. This Sarge cock ring has an inner diameter of 57 mm. A cock ring should feel tight but never uncomfortable. Don't wear it longer than 30 consecutive minutes.
