A vacuum constriction device (VCD) is an external pump with a band on it that a man with erectile dysfunction can use to get and maintain an erection. Device use may bruise or rupture the blood vessels within the penis or scrotum, resulting in petechiae (a small purplish spot on a body surface, such as the skin or a mucous membrane, caused by a minute hemorrhage), hemorrhage (flow of blood from ruptured blood vessels), or the formation of a hematoma (localized swelling filled with blood resulting from a break in a blood vessel).
The saying use it or lose it” is true and the penis needs to be exercised to keep it functioning properly, esepcially as you get older , take medication that may have sexual side effects or have a health conditoon that may impact upon your sexual function.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there - penis pills, creams, brutal stretching exercises , horrific-looking devices, and penis surgery.
Use of a constriction ring may aggravate already existing medical conditions such as Peyronie's disease (the formation of hardened tissue in the penis that causes pain, curvature, and distortion, usually during erection); priapism (persistent, usually painful erection of the penis as a consequence of disease and not related to sexual arousal); and urethral strictures (urethral stricture is an area of hardened tissue, which narrows the urethra sometimes making it difficult to urinate).
But many of the men who use these devices probably don't need to. "Penile dysmorphic disorder," characterized by the belief that one's penis is small penis pump despite all evidence to the contrary, is a real condition that researchers are starting to treat as seriously as body dysmorphic disorder.
The Penis Pump uses vacuum treatment on the inserted penis in order to improve penile tissue and allow more blood-flow to his member which will increase sensitivity in the short-term and if used regularly, can result in increased penis size and erection strength.
Pumping erect gives you a bigger dick (more fluid retention), but what I noticed was pumping flaccid gave better expansion of blood chambers (corpus cavernosum, etc), you can tell once erect if you squeeze the shaft, through the squishy fluid once you feel the hard blood chambers, it was bigger in size.
