How can i get a big penis..?

No good answer: Penile enhancement surgeries are not a good idea in most cases. Additionally, there are no drugs or herbal remedies that will increase the size of one's penis. Take heart though, probably less than 1% of men have a penile size hat is inadequate to have successful sexual intercourse.

Penis Size: Agree with Dr. Tillet. By age 20 would not anticipate significant further growth of your penis. Be aware that many companies play to some men's desire to have a larger penis and sell lotions, pills or machines that do not work despite promises for penile enhancement.
