Fitting Advice
As always the fit is going to depend on your personal preference and how tight a fit you like from your cock ring. This cock ring is going to give most men a nice grip. But if you are a bit smaller than average or have narrow proportions it might be a little looser. Remember that you ideally want the inner ring to be slightly smaller than the circumference around the base of your manhood and balls.
