How can i increase my penis size
First the bad news: There really isn't any way to noticeably increase the size of one's penis.
Regardless of the claims made on TV and online, pills and creams don't work, and even surgery is likely to add less than an inch (it also involves cutting the ligament that attaches the penis to the pelvic bone, so when erect it points down instead of up).
Now the good news: While many men may think that they are below average size, most are not. The average size of an erect penis is only 5 to 6 inches, so if you're within that size range, you're the same size as most men.
In oddball news, a Canadian doctor, Dr. Chris Culligan, has released a smartphone app called The Predicktor which claims to be able to predict the size of a man's penis by using criteria such as height and finger length.
