It is normal for some men to have a shape to their penis. The way the muscles, fascia and skin develop from birth to puberty shape the final result. No two penises are exactly the same, and that is part of the miracle of human diversity. Some partners report greater pleasure with different shaped and sized penises. I am sure that there is some surgeon out there who could convince someone with a very differently shaped penis to undergo cosmetic reconstructive surgery, but medically the treatment would be unnecessary and potentially very harmful.
