My penis is very girthy and feel that elongation exercises are preferred rather than for girth.
I have so much shrinkage that I prefer to have some length to show when I get nude before hitting the showers after a workout.
Plenty of men in the locker room are very small and I ought not feel inadequate. Regardless, I want to show signs of a healthy endocrine system. This also give me the confidence to perform when I get home to my partner.
Just like muscles, the penis needs time to heal from the stretching.  The stealth helps to maintain the length and seal or cement it into place  w/o the stealth, it will go back to shrinkage and turtle  When my penis gets full it seems to get girthier w/o the stealth use
