As a hanger-I agree.Hanging can be dangerous.Main reason is the shills who claim they hang "20+ pounds" a day for 4+ hours. That's all bullshit.
Hanging is tough on the penis and when you get 10+pounds you are in some real hardcore territory.
Put it this way: An [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]extender[/words] can give max. 6.5 pounds of pressure. For a hanger that is nothing.
Hanging toughens the tunica and makes it difficult to gain length from stretching with other devices.
