Perfect Fit Xact-Fit Cockring 2-Pack, Size #13 Anal Probes and the borosilicate construction meansThe right fit changes everything. Too loose and you lose the effect entirely. Too tight and you are thinking about discomfort instead of what you came here for. When the ring fits the way it is supposed to, you feel the difference almost immediately. Fuller, firmer, more sustained. That is the actual outcome you are after, and fit is what gets you there. These rings are sized in precise 0. 1 inch increments, which means you are not guessing or hoping.
