Constant Testicle Movement

One symptom that my boyfriend has that I have not been able to find anyone on this forum with is strange bouts of testicle movement. I know what muscle spasms look like and this is entirely different. It’s a very weird and consistent spiraling/revolving/rolling motion sometimes for hours on end. It’s painful. There’s nothing I can compare it with to describe the type of motion it is. I can’t even say that “contracting” is the right word. He suffers from all the sexual sides and emotional blunting.

Does anyone else have this or can offer some insight as to what exactly is happening?

I have this as well it’s very odd they move all the time now. I think there may be others here with it as well.
