Look at my "pressing" pix, for example. Plus, I use hand-warmers to overheat my nutlets, and then physically abuse them via squeezing in all dimensions, kneading, and such. For me, the heating seems to lessen pain sensation, making physical abuse of any sort easy and pleasant. Of course, your situation may differ since my nutlets were already shriveled and fully atrophied from a couple years of nonorgasm/nonejaculation before hand. Good luck and have fun!!! And, do let us know how it goes!
