Sensitive and Unwilling Balls

There seems to be a general lack of those two things in most ballbusting porn and it's a big gripe of mine. Most of the male models are so desensitized over the years of hard ball busting that their balls can really take a beating before it seems to have any effect on them. That kind of defeats the purpose of this fetish, at least in my eyes. I find it much sexier for the reaction to be far more realistic, a small knee, punch, or squeeze taking the male subject down rather effortlessly, like in real life. As opposed to the guy standing there with his hands on his hips taking kick after kick and barely reacting at all.

Which leads into my second point. For the taboo subject of getting hit in the very sensitive balls, most guys would try to protect. A guy that is caught off guard (youtube videos of play fighting or pranks) or in bondage scenes where the male is fighting against his restraints to protect his goods is far more attractive to me than a guy that just stands there willingly, or one that holds his cock out of the way for any potential hits.

Anyone else share this same sentiment? Thoughts?

Side note, if anyone has any links or videos where the balls are more sensitive/realistic and/or the busting is more natural where he is caught off guard and or restrained I would love to see them! Thanks for listening to my TedTalk.
