Pumping wrong, need guidance and advice

[Pigpie]

Hello ,
So a bit about me. For the last two years I have been using a vacuum pump, more for the pleasure than gaining size etc.
This is the first time I have actually looked into the correct way of pumping.
So I now know that for the last few years I have been doing it all wrong.
So I have never had a problem with my cock size or girth, without pumping it's 7.5 inches long and 7 inches thick.
As you will see in my pics when it's pumped I can get to 8.5 to 9 inches long and 8 to 8,5 inches in girth.
I have always achieved this by spending hours pumping my cock slowly so it can adjust ,then pumping it to the maximum the tube will allow.
So in my pics you will see that the tube I have always used is only 8 inches long,and my cock is crammed in there in totally the wrong way.
I have a new pump arriving tomorrow which is 11,5 inches long etc.
Also I always wear ball strechers and as u will see in some pics I can pump my balls to nearly 8 inches in length.
So here are my questions.
I now know that I have been pumping way to hard " I've never had a gauge before tomorrow.
I always have red spots, and sometimes disfigured tissue around my cock.
I need some help with a routine, ie pressures and times etc, how long for etc" I do like to pump for hours "
I'm always looking for more length and girth, so what would be a good routine?
Any advice would really be appreciated, for the first time in two years I want to learn how to do it correctly.
Attached are some pics of what I normally achieve.
Thank again for your help
