This is a normal physiological and anatomical fact and so should not cause any worry. It should be remembered that the penis is more like a balloon which is fixed to the pubic bone and that it gets the erection from the blood that rushes into its veins and that leads to an increase in size, and since the parts that are attached to the bone donot contain that much of blood as the parts that are free and in front, therefore the anterior portions become more swollen than the portion that is fixed to the pupic bone.
Some people think that a penis can be make erect at will, just like a finger or an arm, and when this does not come about they start to worry about their sexual health. It must be remembered that an erection cannot be caused on order or wish. This is physiological process much like appetite. Just as hunger or appetite cannot be caused at will, similarly erection cannot be caused on order or wish. This is a physiological process much like appetite. Just as hunger or appetite cannot be caused at will, similarly erection cannot be caused at will. Just as proper physiological and environmental circumstances are necessary for causing an appetite, in the same way, proper physiological and environmental stimuli are necessary for causing erection. A person will feel hungry when a few hours have elapsed since his last meal or when he is presented tempting, tasty food and the environment is also conducive. In the same way a person will have erection when he has sexual thoughts, some time has elapsed since the last sexual activity, and/or the environment is sexually stimulating.
In infancy and childhood the penis is small, the blood supply of which is limited and therefore the superficial veins are not visible, specially due to the excess of subcutaneous fat, but as adolescence appears, anatomical changes occurs, and the subcutaneous fat disappears, the veins enlarge and become visible. This is a normal change but most youngsters think that this is an abnormality and this anxiety has been fueled by the Hakims and other quacks who consider it a serious disease.
It must be remembered that veins are present under the skin all over the body in places where there is more subcutaneous fat these veins are not visible, but in places like penis, where subcutaneous fat is almost absent, the veins become visible. Similarly the vein are visible on the back of the hand and therefore the visibility of veins should not be considered as an abnormality.
However, there is a condition which occurs in testicles or rather on the skin of the scrotum, in which bunches of veins become visible, which is known as varicose veins and if this is present the doctors should be consulted and these should be removed, for sometimes these can cause infertility.
