Neck pains during masturbation?Watch
I thought it could be because there's a lot of blood rushing to my head, but surely if I'm still in the middle of masturbating, the blood should still be in my erection, not flowing back out of it, right? Or maybe there's not enough blood going to my head, so my arteries open up to compensate or something? Could it also be something to do with being dehydrated, or blood pressure?
Any thoughts? It's quite scary because it really feels like a vessel is going to burst.
Whenever I'm doing it my top of back and neck aches and I feel the urge to crack it.
