The Penis – Parts & Anatomy Down There

The penis is a reproductive sex organ. Lots of people who have one themselves are aware of what penises may look like, but there’s more to it than meets the eye! The penis is part of a complex reproductive system, and it serves more than one purpose.

Parts & Anatomy Of The Penis

The penis is made up of several parts, which all have different names.

  • The glans, or head. This is the “tip” of the penis. It may be circumcised or uncircumcised. If it uncircumcised, it will be covered by a thin layer of loose skin, known as the foreskin. When someone is circumcised, the foreskin is surgically removed and the skin of the glans becomes drier.
  • The shaft. This is the length of the penis, leading from the base to the glans. Inside the shaft are two columns of tissue called the corpus cavernosum. When someone with a penis gets an erection, these columns fill with blood. This is what makes erections stiff. During an erection, a third column of tissue also fills with blood in order to keep the urethra open. This is called the corpus spongiosum.
  • The urethra. This is the tube where pee comes out of. The opening of the urethra is in the tip of the glans. The urethra also transports pre-cum and ejaculate.

Below the base of the shaft are the testicles. These look and feel like two round balls covered in loose tissue. The testicles are where sperm is produced. They also help the body produce and regulate certain hormones, like testosterone.

Is my penis normal? How can I tell?

Penises come in all shapes and sizes. It’s important to know that most penises don’t stop growing until the end of puberty – which can last until you’re 25!

Lots of people worry about whether or not their penis is “normal”. There’s no “right” or “wrong” way for one to look. Penises of all shapes and sizes can feel and give sexual pleasure. Some penises are curved, while others are straight. Some are thick, while others are long. The important thing is that your body is healthy, regardless of whether or not it looks like someone else’s body.

There are some medical conditions that can affect how a penis looks. Many of these medical conditions can affect your ability to get an erection, have an orgasm, or do other things with your penis. If you’re having pain or discomfort when you do things like masturbate or go pee, it’s a good idea to speak to a doctor. They can tell you what’s going on, and help find solutions. You might also want to see a doctor if you notice changes in the skin on your penis, like a rash. Other things it can be good to talk to a doctor about include if your foreskin feels very tight, or you often have a hard time getting erect.

Understanding and caring for your body

Knowing about your reproductive organs and genitals is part of understanding how your body works. Having this information can help you identify health problems earlier. It can also make you feel more confident about your body! And it can help you learn what feels good for you.

Taking care of your penis is like taking care of any other part of your body. You should wash it gently when you take a shower or bath. Use a mild soap, like you would on any other sensitive body part. Soaps that contain certain ingredients, like eucalyptus, can irritate the skin on your glans. Try to pay attention to how it feels when you pee, have sex, or masturbate. It’s also a good idea to check your testicles for lumps once a month, especially if you’re an adult.
