You shouldn't use a penis pump because they don't work.
Pumps are meant for men who have trouble getting an erection. They DO NOT MAKE YOUR PENIS LARGER.
Your penis does not have muscles like your arm that can be 'grown' or developed. It's mostly a bunch of soft tissue with blood running through it. A penis pump can, at best, drawn some extra blood into the penis causing a larger erection for a few minutes, but nothing long-term or permenant.
It CAN lead to permenant damage, scaring, ruptured blood vessels and trouble getting an erection.
Men have been looking for ways to enlarge the penis for CENTURIES. I promise you, if there was a way that actually worked it would not be a secret and EVERYONE would do it, and all guys would be running around with foot-long dongs. Guys aren't, because nothing can increase the size of spongey tissue. Drawing a little bit of extra blood into the penis is just making it swell up. It wont make you bigger in the long run.
