Penimaster pro questions

[Trashboat]

Hello. I've had Peyronie's for about 19 months. And have several plaques all over my penis. It hasn't made much of a difference in the size, or shape, but there is a slight curve. My first question is about the pump. I don't know how to use it, how do I close it? If I take the ball pump off the valve, the air immediately leaks. Any advice there would be appreciated. I'm about 6 to 6.5 inches in length. How do I configure the rods to be that length? Lastly, the hose seems to be the best option from what I've heard. How much should I suck in? I've heard 8 hours is the max you should wear the device a day, do you agree? Any help is greatly appreciated.
