Male Anatomy

The penis

The penis is the male sex organ. There are no bones or muscles in the penis, and it has two main jobs: to wee (urinate) and to have sex.

The penis has a shaft which is surrounded by the foreskin (a hood of loose skin that surrounds the penis). On most men both testicles hang outside the body, just behind the penis in a small pouch of skin called the scrotum.

The glans are highly sensitive containing about 4000 nerve endings. 

What are Testicles? 

Testicles are the body’s sperm factory. Testicles store and produce sperm, starting at puberty and for the rest of your life. They also release testosterone- the hormone responsible for the many changes throughout puberty. 

The sack that holds the testicles is called the scrotum and its what keeps testicles at the right temperature. If it’s too cold, the scrotum muscles bring the testicles closer to the body. If it’s too warm, the muscles let the testicles hang away from the body. The scrotum is covered with wrinkly skin and hair. Not all scrotum’s look exactly alike-they can be big, small, have a little or lot of hair, and vary in colour.

Most males have two testicles, and one will hang slightly lower than the other.

What’s an erection, and why does it happen?

An erection is when blood flows into his penis faster than it flows out, causing the penis to get larger and harder, this is an erection.

Erections (boners/stiffies/hard-on’s) can come and go without warning. Appearing and disappearing at a moments notice.

Normally an erection occurs when a man is sexually excited, but can often happen when you’re not (sitting on a bus)

 

 

Is my penis normal?

Unless your penis hurts or feels uncomfortable, it’s pretty safe to say it’s normal. At some point in puberty, penises start to get bigger. this happens at different ages for different people, but it happens to everyone.

A lot of young men worry about the size of their penis, a penis carries on growing until you are about 21. There is no such thing as a “normal” penis.

 Everybody has a slightly different size and shape penis. The size of your penis depends on your genes, just like the size of your hands, feet, and eye color.

Keep in mind, penis size has nothing to do with ‘manliness’ or sexual ability.

What is a foreskin?

The foreskin is a sleeve of skin that surrounds the head of the penis, when a man or boy gets an erection the foreskin stretches exposing the head of the penis. Boys and men need to make sure they wash under the foreskin.

Some boys and men are circumcised (this is where the foreskin is removed) this is normally for religious reasons, but can also be for health reasons. This makes no difference to a man ability to wee or ejaculate.
