How Do Vacuum Pumps Work?
Vacuum pumps work by sealing the penis in an airtight tube and removing the surrounding air. The negative pressure then pulls blood (and lymphatic fluid) into the penis and inflates it. The process takes about a minute and the results can be very impressive. The trouble is, as soon as you remove the tube, the penis wants to revert back to its normal size. You can staunch the outflow of blood and lymphatic fluid by fitting a constriction ring around the base of your penis. This generally allows the penis to maintain its expanded girth for a few minutes - sufficient for insertion and at least one change of position before you have to pump it up again.
