I agree with bug , what happens if you start to get an erection ? I wear my P.E. Weights at work all the time , and I do get erections there , helping all the hotty Milfs that come into the store . But with the P.E. Weights , there are a few inches left in front of the weighs for the blood to go , and it ends up being like a mild clamping session . With that many rings , seems like there would be no place for the blood to go , other than your glans . Could be a little dangerous .
And speaking of dangerous , I do not like the looks of those sharp ended little pins they are using for securing the rings together ! Yikes ! From my experience with rings and things , the smoother and more rounded things can be , the less pain is involved .
