Is this a girth exercise?

YES I SEARCHED. I could not find a good answer

Are these exercises for girth?

Grip at base of shaft semi tight, with other hand grip above base slightly, move upwards while tightening and un-tightening your grip to trap blood and expand the glans.

Also will just plumping your penis up by squeezing at the base over and over again do anything? That is what I mainly do for girth.

It’s a girth exercise….wonder how effective it is though if you don’t even have a semi while doing it.

Your exercise does not sound like the best use of you time. There are more effective exercises out there so why not do them instead?

It sounds pretty much like clamping but with your hand. I would rather do jelgs until I have conditioned my penis enough to use a real clamp.

As GG said you are most likely wasting your time.
