Again, for me, I was not able to wear it for more than a day or so continuously due to my foreskin swelling, but the effect it had on my headspace was astonishing. As with all things, YMMV.

If you look closely the points in the picture look about as sharp as your average nail; sharp enough to make you feel a prick if you’re jabbed with it, but not sharp enough to break skin and draw blood unless it’s pressed quite strongly, or scratched across the surface. I guess it would depend on the degree of constriction, the size of your junk, and the hydraulic pressure of your stiffie. The ultimate “your mileage may vary” I guess!

Also one could blunt those spikes very quickly with a small file should they prove too sharp. Or there are fancy versions sold with blunt and sharp spikes that are individually adjustable for length — those you could tailor to any sensation you wanted.

These types of devices are a lot of fun, it really changed the way I thought and behaved, I definitely did my best to avoid anything that might start me getting aroused.

The problem with the enslavement ring type for me was that it takes a really long time to get it on (30-45 minutes), you have to be 100% flaccid, and I found that after a solid 24 hours of wear my foreskin had started to swell up so it was obviously a little too tight on me (but looser and it might slip off).

I’d like to try one of the hinged ones as a short-term/play scene torture device, because despite my best efforts, all Mistress had to do was reach down and fiddle with my penis a little bit to bring me to an agonizing attempted erection.
