Does Pumping leave permanent Girth Gains

I was considering on purchasing a Penis Pump because my base girth and mid shaft is on the small size, kind of like a baseball shape effect at 4.4-5.0”. Because I could not post in the pumping section I was hoping to get answers here.

Does pumping really work?

How long/routine pump should I go with?

Does it leave permanent gains?

My base girth feels more like tendon on the outskirts then excess meat will this affect my gains?

How much gains have you had on EG and how long have you done it for?

Thanks in advance!

I have pumped for over 10 yrs and the only true lasting gains I had were in girth. When I started pumping my girth was 3” not real fat. After 10 years pumping I have a girth of 5.75”. But didn’t pump everyday. I would take long breaks I’m my pumping. Pump a couple of weeks then not pump for a couple of months. Now I’m using an extender and my girth is almost 6”. I use my extender almost every night for 2 to 6 hrs.
