Well it pushes more blood into your penis than can flow out at the time, resulting in more inside pressure ;)
If this does anything or not is something only you can say.
Some people say it does, some say it doesn’t.. YMMV.
One thing I can say about it is that it’s great for getting the healing in your penis going (especially if you edge without using your hands)..
Provided you don’t ejaculate that is.
I think it’s a good pre-/post-exercise for jelqing or maybe clamping.

She said you had a small dick huh? Well just remind her of what Tom Arnold said about his soon to be ex-wife, Roseanne, when she said very publicly that he had a little dick - "Hell, even a 747 looks small when you put it in the Grand Canyon".
