What is a mans penis made out of?

Answer 1

Penises are formed out of several tissues. On the inside, there are three shafts of something called "erectile tissue": this tissue, when it fills with blood, expands a great deal, and this is how penises become erect. These three shafts are surrounded surround by normal ligament and skin tissues (although the skin of the penis has a lot of extra nerve endings). Running through the center of the penis is the urethra, a tube through which both urine and semen are moved out of the body. The tip or head of the penis is a special formation called the glans penis; this head is formed of erectile tissue and has a large number of nerve endings and is very sensitive. The meatus or tip of the penis at the very end. Men who are not circumcised have a foreskin, a sheath of skin that protects the glans penis when the penis is not erect. The penis also has several glands that excrete hormones, skin oils, and smegma.
