Penis enlargement is defined as all means and methods used to temporarily or permanently increase the size of the erect penis and its erectile tissue. Often the word is used in conjunction with a surgical penis enlargement, but it is not limited to surgical means and also includes manual training like jelqing, certain foods and supplements, devices and pumps to stretch the penis.
Like extenders, pumps are suitable for all kinds of users. However, while extenders affect length alone, pumps affect both length and girth. Also, you have to allocate a certain time per day for a pumping routine. Intermediate users usually add 10-15 minutes of pumping time to their workout while advanced users can prolong the duration to half an hour. 2-3 rest days per week are required to facilitate recovery.
