If you've got balls, stuff them into this amazing hunk of metal and show your partner the "REAL" in real man!!! To fit properly, a cock ring should be loose enough to get on and off easily, but a bit snug to work its magic once the blood starts pumping.

To calculate the minimum size of a cock ring, cut a strip of paper or ribbon no wider than 1/4 inch. Starting from the top of your penis at the base (where it meets your body), wrap the paper under your scrotum, bringing it around to the starting point. Mark the paper where it meets. Measure that length, then divide by three.

The correct diameter of the cock ring you should order is approximately one-third of the length.
