Sounds like I’d pass out from the pain if I tried anything like this.
…
I had weird friends in college, which was appropriate since I was (and still am) pretty weird myself. One such friend, who was heavily into body piercing & body modification (talked regularly about wanting to split his tongue) took it upon himself to warp my fragile little mind by showing me unsolicited pictures of sounding. When I recoiled in horror and shut my eyes, he then proceeded to tell me of cock & ball torture enthusiasts who supposedly stick a sounding rod in their urethra and then hit their dicks with a hammer. He was a little too excited when describing this to me, which makes me wonder if he ever tried it himself.
