Can you guys tell me how big can penis enlargement surgery get you and what is the min. age?

Quackery: Does not work. Surgery which divides suspensory ligaments at base of penis can give false impression that penis is longer, it won't be & won't work as well. Surgical implant of silastic under penile shaft skin can make penis fatter bur reduces sensation, there is risk of infection & advise against. There is more to sex than penile size. Supportive partner is much more important than penile size.
