I was wondering if any of you know or have any experience with placing genitals in very cold or scalding hot water to temporarily numb the penis/testicles for periods of time?
I remember reading something about it YEARS ago, but never have actually seen anything sense.
My ideal goal: dip my testicles and penis in either of these things, and feel numb and unable to get an erection for some time, but not have it be permanent (this is just fantasy play stuff)
Any ideas, comments, or suggestions?
