Puberty for boys

Puberty is when your body changes as you grow and develop to become an adult. These changes can affect you in different ways. 

What happens during puberty?

Puberty is a series of changes your body goes through as you grow.

Your body produces hormones which change your body and they can also affect your emotions. Getting used to all the changes can sometimes be stressful.

Everyone is different and will start puberty when their body is ready but it's common for it to start around age 12-13 and for some this can happen earlier or later.

The changes to your body take time and puberty lasts for different lengths of time for different people and can last for up to 4 years. This is completely normal and doesn't mean there's anything wrong with you.

8 things boys will experience during puberty:

  • Your voice gets deeper - some people might refer to this as your voice "breaking".
  • You'll get taller, bigger and more muscular.
  • Pubic hair will start to grow - around your penis and testicles (balls).
  • Your penis and testicles will grow larger.
  • Hair will grow on your face and under your arms.
  • Sexual thoughts and feelings.
  • You might get spots and start to sweat more.
  • You might feel more irritable or moody than usual - this is because of changes in your hormones.

what to expect during puberty

You'll go through lots of changes during puberty. Some changes are obvious to other people, like growing taller, and some only you will know about. 

Masturbation

Masturbation is when you touch your body and your genitals because it feels good or pleasurable. Both girls and boys masturbate and it's completely natural.

Your penis

Penises are all shapes and sizes. There's no right size or shape. Whatever size your penis is, you're normal. A penis can also change size. Sometimes it might be soft and small. Other times it may get bigger and harder.

A cold temperature can affect the size of a penis and can make it smaller, but this is only temporary until it warms up again. Some penises are straight and some might be curved slightly. Both are normal.

Penises in porn

Sometimes watching porn can start to change the way people see real life. In porn, the actors often have very large penises. Some of the men in porn have had penis enlargements – this is an operation to make their penis bigger.

In real life, most males have much smaller penises than the actors in porn. Try not to compare your body to others. Everyone is different.
