Imagine if a finger ring only came in three sizes equivalent to the circumference of a dime and a quarter and a dollar coin how would they fit? Well until now, cock rings were sized even farther apart than this! No wonder finding a good fitting cock ring is near impossible. Perfect Fit has developed the first cock ring sizing system designed to fit you without too much pull but with enough restriction to be truly effective.
