I’ve done a lot of sessions over the years and never had an issue. It’s certainly possible to get a serious injury. I feel like that’s been pretty well documented. But I do think serious injuries are pretty rare.

I also think ballbusting has been around for a long time even outside bdsm. I know in my high school/college days it certainly was a favorite target for many of the women I knew. I never heard of any of their victims having a lasting injury other than the brief embarrassing 10 mins of being incapacitated lol

Personally, I find I don’t need a crazy intense session which probably helps reduce the risk. It doesn’t take a whole lot to drop me these days, lol. But in years past I did some pretty intense sessions without any long term damage.
