Imagine pinching the sides of your penis between your finger tips and pulling outwards to make it wider. The suction will hopefully pull on the tunica rather completely the skin.Hung21 yes I think it would be a challenge to make sure there is enough skin so that you’re stretching the insides and not the skin. It’s a common problem with hanging in general. As far as “tearing your penis open”, the outwards pressure is not different than getting an erection or doing a jelq, except its pulling from the outside rather than pushing from the inside, similar to hanging vs. jelqing. Hanging pulls from the outside, jelqing pushes from the inside. The penis is made to handle the force of an erection in all directions.
Yeah but correct me if I’m wrong. My physics suck.
Air starts off at a normal pressure which is normally close enough to 0hg that detailing that isn’t pertinent to this discussion. In either case, it wants to remain at this normal pressure, and it can demonstrate this by when you suck air from a bag and the air pulls at the sides of the bag, compressing it. Ah, so there’s that 0hg it’s trying to keep.
Pumping is the same, except it’s pulling at any surface possible, one of them gives a bit (your penis) the other does not (the tube)… and it can’t regain that 0 hg unless you let air back in. So generally, I think, when someone says they are pumping at 2-3hg, then that’s what pull their dick is experiencing.
