Pumping does generate permanent gains.
Most people wear an extender where they have privacy. Wear it for 45 min- 1 hr, take it off, massage your dick then put it back on for another hour. I’m unaware of anyone who ever wore an extender for 4 hours straight. Once the dick gets cold and numb the extender needs to be removed to restore circulation.
To wear it in public one needs to have very baggy pants/shorts.
I have over 500 hrs, prob close to 600 in an extender. I had no results from it. There were times when I was wearing it I went from all is well to my dick screaming to me to GET THIS THING OFF NOW! From these experiences I never attempted to wear it in public. Your results may be different.
