Hi,
Penile size varies and depends on several factors including your genes, nationality or race and even environmental issues like culture, diet and exposure to chemicals. Various studies have listed average flaccid length of four to six inches. Smaller sizes can be attributed to deficiency of pituitary growth hormone and/or gonadotropins, mild degrees of androgen insensitivity, or a variety of genetic syndrome. For proper evaluation and to ease any worry, check with your doctor. Take care and best regards.
