This sounds weird, but my penis has been vibrating recently. It usually starts when I masturbate. It’s a very strange sensation, kind of like when my cell phone is on vibrate, except it’s not my cell phone. I’ve had weird energy effects from kundalini yoga before, even projecting energy into a couple of my ex-girlfriends while receiving oral sex from them, but nothing like that has happened in a couple of years. What the hell is this? I doubt anyone on here knows, but it’s worth a shot.
