For boys, hitting puberty tends to mean hairs in weird places, changes in the penis department and a deep voice like the guy off the film trailers. Don't worry though, it's all normal...
What is it?
Puberty is when your body changes from a child to an adult. Boys start puberty around 12 years old, but it can happen earlier or later.
The length of time you're in puberty is different for everyone. For some, the changes will take a couple of years, for others it might be as long as four years. It's completely normal.
- The first sign for most boys is that the testicles get bigger. Within about a year, the penis will start to grow larger.
- The body will start producing more sex hormones, so you have more sexual feelings and more erections. Boners can appear when you're not even aroused, and sometimes at the most awkward moments. Great. This can be embarrassing, but usually no one notices.
- Boys also begin producing sperm, which means you'll be able to ejaculate. You may even ejaculate in your sleep - this is a wet dream.
- Hairs crop up all over the place - especially on armpits, legs, arms and around the penis. Your face will get hairier and you might grow hairs on your chest too.
- The whole body grows bigger and more muscular. The arms and legs usually grow first, which can feel weird, but the rest of the body will catch up.
- Your voice will start to sound lower. The tone might wobble, crackle or be difficult to control at first. This is what people mean when they talk about boys' voices breaking.
- The extra hormones will make your skin get more oily, and some people get acne as a result. If this starts to become an issue you can talk to your GP. Most boys will start to sweat more too.
- Some boys get a swelling underneath their nipples, which can look like the start of breasts. Don't panic though, you're not growing boobs. This is only temporary.
