Finally got this jelking thing down, and noticed a new PI tonight but can't tell if it's a good thing or a bad thing. Coming up to the end of a 50 rep set, it feels like the very tip of my glans wants to explode. Similar feeling to if you continue rubbing the glans after ejaculatory when it gets sensitive as hell. Not painful at all and feels kinda nice. To me it seems like a positive one, but couldn't find anything after searching for a while.
