I have a lot of experience with prostate self-massage. I play with inserting large toys, even created a technique for self-fisting. But for day-to-day experiences, certain bowel problems have me cleaning my ass a few times in the morning and also in the evening, with a Japanese computer-controlled bidet. With all that water and washing around with my hand and my generous dimensions there, my hand is in there a long time, stirring around my ass and reaching in as I clean.
For me, it's not just the sensations of my prostate that appeal to me: all the nerves and parts around there are so lonely for love: a kind of loneliness being satisfied through being stimulated all around my dick, balls, ass and prostate (and mouth, neck, face and nipples, too!!) I enjoy the amazing hunger of those lower chakras!
I sometimes fantasize about asking a sex-worker to help me with some kind of fisting. Then I fuck myself in various ways, later panting after orgasm, I think how easy to tailor the experience to myself. Every time a little different. I always ask, “What turns you on? What do you want?” It is exciting to want something like an enema or large (prostate-stimulating) toy the receiving of which I know will involve some discomfort.
The self-fisting technique is to insert a good-sized toy, then reach in with your fingers and wrap them partially around the toy. That is your fist, enjoy!
I find the strongest pressure on the prostate comes from a large, firm toy. I love it, sometimes double over from the strangeness of it.
I also like having a toy inside, and sitting my crotch on a large dildo laid horizontal on the seat of a chair. Sit down and go wild. The extra stretching and pressure on the prostate is incredible. Be careful setting your weight down. You might be surprised by the strong feeling!!
