What are some excersices i can do to enlarge the penis?

Buyer/Doer Beware: Little legitimate scientific research has been done on non-surgical penile enlargement; existing claims of significant and permanent enlargement are generally anecdotal, unverified by objective research, and can be biased by the interests and emotions of the source. At present, there is no proof of any non-surgical technique that permanently increases either thickness or length of penis.
