From: Austin, TX
I share similar concerns about long-term injury and do not seek this activity. It might be a whole different story once I am done having kids ;-)
I am not sure how much reliable data there is in the medical community about intense trauma to the testicles. I imagine there might be data from sports medicine or accidents.
There are forms of kicking that are less intense. Some (kicks from behind) deliver the primary impact with the instep on the buttocks with secondary contact against the scrotum. There might also be showmanship in some of what you see. I once saw intense kicking in a fetish show but it turned out the guy was wearing an athletic guard under his pants. Indeed there are instances where the sub is naked and there is no guard.
There are certainly instances of irresponsible play without thought about safety or consequences. Just this weekend I heard of an account of a domme who kicked an experienced CBT player. It may have been her first time--I am unsure but know she is new to BDSM in general. She delivered a hard kick with the toe of her boot. I was told that the man had blood in his urine shortly thereafter and left to receive medical care after letting one of the event organizers know what had happened. It is a second hand account but a believable one.
While there are countless threads that seek wank material, I sense this one does not and I am willing to give the benefit of doubt. I think the thread raises a good question: how should a sub gauge how knowledgeable and responsible is the dominant in question. And , what thoughts about safety and responsibility do have dommes who engage in this particular type of play--how did they go about finding out how far they can go?
If someone knowledgeable in this technique responds, it would answer the OPs question and let someone new know how to go about learning this technique.
