Hello, I went through your query, first of all what you have to understand is it is not possible to increase length of your penis and to increase size Of your testis. If you have normal secondary sexual characters and I you have normal sexual urge to opposite sex then don't worry. Your penis size is enough to experience all the sexual pleasure and to satisfy your partner. So don't worry, avoid smoking and drying, if any. Have health diet including more of fresh fruits and vegetables.
