It's definitely not a myth that ballbusting can cause damage and possibly even permanent injury if done incorrectly. Like many other things we do, there is an inherent element of risk associated with this activity. It isn't "my thing" or something I know a whole lot about, because I generally avoid it. That said, I'm sure that in most cases, with a knowledgable and reputable Domme, it is relatively safe. I've done it once. The Domme joked about having to take her boots off first so she didn't put me in the hospital. She could tell I was terrified, so she was very gentle with me and it was no big deal.

I do have experience with extreme ball pain, however, and I know I don't like it. In my younger days, I had a physical altercation with a roommate where he punched me very hard in the balls and I punched him extremely hard in the head. It was an amusing picture, me groaning in agony and holding my balls, while he groaned in agony holding his head. The blow was *extremely* painful and as others have shared, I felt quite nauseous for a while afterward. Oddly, it took an entire week for my balls to turn purple. I had no idea what was causing the discoloration at first and called my doctor in a panic. He asked if I'd sustained a blow to the testicles recently. At first, I said no. Then I said; "Wait.
