New to Jelqing

I have just started jelqing. Two questions. First, does it work for older men too? I’m 60. Second, I heard that gains are not permanent true or false?

First - Yes
Second - False

Welcome aboard. It works for all age groups and once you cement your gains, they are permanent. Cementing is a process of continuing to PE for a couple of months following your gains in order to lock in a new size memory for your cock. So don’t gain an inch and quit. Continue on for a while.
