penis
[pe´nis]
the external male organ of urination and copulation.
The body of the penis consists of three cylindrical-shaped masses of erectile tissue which run the length of the penis. Two of the masses lie alongside each other and end behind the head of the penis. The third mass lies underneath them. This latter mass contains the urethra. The penis terminates in an oval or cone-shaped body, the glans penis, which contains the exterior opening of the urethra.
The glans penis is covered by a loose skin, the foreskin or prepuce, which enables it to expand freely during erection. The skin ends just behind the glans penis and folds forward to cover it. The inner surface of the foreskin contains glands that secrete a lubricating fluid called smegma which makes it easy for the penis to expand and retract past the foreskin.

penis
The male organ of copulation containing the URETHRA through which urine and seminal fluid pass. The normally flaccid penis becomes enlarged and erect by virtue of three longitudinal cylindrical bodies of spongy tissue into which blood can flow under pressure under the influence of sexual excitement or other stimuli. One of these bodies, the corpus spongiosum, surrounds the urethra. The other two, the corpora cavernosa, lie side by side above the corpus spongiosum. Erection physiology is mediated partly by nitric oxide.

Q. what is the avrage 12 yr old penis lengh
A. Guys normally develop at different times. Some may start developing as early as 9. Others may not start developing until 15 or even later. The age at which a guy starts to grow varies from person to person. It all depends on when he enters puberty and his hormones start doing their thing.
Q. Is my penis supposed to look like this? A few years a go I was masturbating and had a sharp pain and stopped. It was swollen. The doctor said it was fine, no structural damage it was probably just irritated. Two years later I still have extra foreskin. It doesn't affect my sex and not noticeable with an erection. I am just curious... what happened?!?!
A. i'm no expert on this...but i wouldn't worry about it too much, if it looks fine erect and doesn't hurt - it's all good. and unless you plan to run naked in barbwired field- it won't give you any problem. i guess it's the body reaction to excess usage, like your body gaining hight if playing basketball while growing.
