I'm not going to list my stuff right now though it would all be repeats of the stuff you all have already posted.
I agree, this can get me hot, I am going out shopping and AI will be eyeing everything that might have some possiblity. I thought of perhaps frozen grapes as I saw someone put that in here but didn't say frozen. Seems if not frozen you'll pop them with your finger trying to get them into the tight muscle there.
One thing I hav e done that I didn't see anywhere here is a coat hook. Yes, a simple coat hook that you put on the wall that has two hooks. Works well to massage my prostate while the lower hook can be used elsewhere.
I got one from home depot but I am going to walmart to see if they have any different styles or other things to work on my prostate.....you are only limited by your imagination.
