My girlfriend and I used to original OhNut with some difficulties. I was too wide to comfortably wear them for any length of time and would cause some pain when I would take them off. And never mind easily adding or removing rings without a mood killing process. We tried several different methods to "stretch" the rings out before playing to no avail.
I reached out to OhNut and heard about the wider versions. We tried them out and were blown away. I could add and remove rings without a hassle, they didn't constrict and cause pain, there was no red or white ring around the shaft after using them, and they helped me prevent from hurting my girlfriend in most positions. Suddenly positions we thought were impossible were now completely possible.
Ditching the anxiety over whether we would be causing each other pain made it so much easier to get into the right head space to truly have a great time in bed. An absolutely amazing product for both men and women.
