Try an cheap air pump for the begginning it would give you some temporary girth gains kind of like 0.5cm-1cm in erect girth that if you pump anywhere between 20-60 minutes at medium to high pressure (5-10hg) , at least that's what i've got from , also on long term you can expect some good results if you're a newbie to penis enlargement and also if you do a routine , i just did the pump 3 years ago i would use an pump and i was 16.5 cm when i entered the tube , 17cm pumped inside the tube , in time with just the pump use regularly for a while then don't use it for a couple of months , time off and on for like 3-4 years , right now when i enter the tube i'm 17.9-18cm , and inside 18.4-5cm ..So i guess it works but it's a lot of work , i'm a newbie by myself just gotta get my first extender and work on lenght but just by pumping for 20 minutes sessions 1 to 3 times a week at moderate pressure ( at least 5 hg ) over the course of a few years doing pumping time off and on , i've gained 1.5cm .
