How would it feel if you'd just gotten out of the shower, and your wife suddenly grabbed your flaccid penis and started roughly and repeatedly yanking it as if she was trying to jerk you off? Would it be painful, or at least shocking and uncomfortable?

Ahh this is a bad example. Because those kind of touch does feel good. You cannot tell us what is rough jerk off. Any touch that doesn't involve crushing our balls feels good. If my wife suddenly started to roughly jerk me off I would be turn on. No seriously get turned on. Any touch, soft or rough by the penis is a trigger to the brain that it's go time. It's a turn on. The only part you got right is that it would be shocking.

And you are making this so complicated. Just say don't touch that hard. My wife doesn't like getting touch hard. She just say don't do it. Then I never do it. Pretty simple. Idk maybe you guys are dealing with deaf men who cannot understand don't do it.
