Before I answer your question I would like to get some more information:
The size of the penis is considered a hormonal issue if the other features like lack of voice break at puberty , no hair in underarm and pubic areas , central truncal fat distribution.
If you have any of the above mentioned issue then it is a hormonal issue.
Otherwise it is just an anatomical / structural issue.
Please do remember that you can please any woman even with a 3 inch erect penis and you do not have to worry about the size . Do not be embarassed about the size of the penis . It is a very common to have a 3 inch erect penis in men.
