Expert Answer:

Penis is the male organ which serves the passage for sperms. Sperms can be transferred inside the female’s body only when the penis is erect. Penis becomes erect under the influence of sexual stimulation. During sexual stimulation, the blood vessels supplying blood to penis dilate and thus large amount of blood enter the blood sinuses making the penis erect.
