Hi there!
A few months ago, I bought myself a Progasm Jr. I haven’t had much success with it so far, just mild anal pleasure. That said, I kept trying in the hopes that my body would eventually get used to it, taking from the accounts of people on this sub and other websites. Here and there, I read that refraining yourself from masturbating the usual way for a few days would make you more sensitive to pleasure in other parts of your body.
So I gradually started to space out my masturbation sessions for longer and longer periods of time, and when I felt like I wanted to jerk off, I made sure to always plug in my Progasm Jr, and only ever use my hands when the frustration really got to me. Eventually my toy began to move on its own while I was watching porn and I did start feeling some other kind of pleasure from that, but nothing too substantial. However, something different happened today.
As I usually do before any session, I went to the bathroom to empty my bladder. It would seem, however, that I did a poor job, as I felt the urge to pee half an hour in. I didn’t want to end my session that early, so I pushed on despite the risks, and I began experimenting with that feeling. I tried to concentrate on the area where the urge to pee was coming from, and little by little, I switched focus to a spot right under it that felt really good.
