How protective are guys of their testicles?

My boyfriend loves it when I tie him up in the bedroom. We have a few different restraints etc but a few days ago I just used 4 pieces of rope to tie him onto each corner of the bed so he was spread out nice and wide. We have chats between kinky sex to tell each other what feels good and what doesn't. He told me he wishes I would make him fight the restraints a bit more. For example if I tie him up and give him a blowjob he kind of doesn't notice the bondage because he doesn't feel like he needs to move around. In the midst of our bondage session I started lightly flicking and slapping his testicles. Not enough to cause pain but enough to give him a little wakeup jolt. It worked really well and it was like he had an involuntary reflex to try and close his legs or move his hand each time I flicked them. I even alternated between the left and right testicle just to keep him guessing. I never knew he would be so extremely jumpy with it haha Would you say all guys are this protective of their balls? It was like he couldn't control it, he just had to jump

It's an evolutionary response. The testicles are the starting points to new life which is the ultimate goal of evolution. All animals will protect the ability to spawn new life at any and all costs which means ep.yimg.com/ca/I/yhst-80707182936312_2271_13945863

Instead of lightly slapping his balls try tickling them. Less chance of accidentally hurting him and the response to try and close his legs will be greater.

yes thats a good idea. I know he gets really ticklish balls. Especially near the bottom where his butt crack starts. But I don't wanna show all my cards at once :)

There are other parts of him that are ticklish. Try running your fingertips down his rib cage. That will make most people want to pull their arms in. That'll make him feel super exposed and helpless. Same with his inner thighs. Suck on those with your mouth. That should get him groaning.
