Puberty FAQ for Guys
What Are the First Signs of Puberty in Boys?
The first thing you will probably notice is that your testicles are getting bigger. The next thing you're likely to notice is that your penis has started to grow and get longer. It may also get hard when you touch it or rub against something. This is called an erection.
Sometimes you can get an erection when you think of something that's sexually exciting. It can also happen for no reason at all.
Your penis and testicles will continue to grow until you get to the end of puberty.
Why Do Boys Smell When They Go Through Puberty?
Increased hormones cause you to sweat a lot more. This can make your body pretty stinky, especially under the arms or between your legs.
Body odor starts early in puberty. Using an antiperspirant/deodorant can help control sweat and stinky odors.
Try using an antibacterial soap when you take a bath or shower. This can help prevent bacteria that can lead to body odor.
When Will My Voice Change?
The hormones in puberty will cause your vocal cords to get thicker and longer. One day, your high-pitched voice will suddenly "crack." This is normal and will eventually stop. When it does, your voice will be deeper, and it will stay that way.
Your voice won't change, though, until you are almost done with puberty.
When Will I Have a Growth Spurt?
A growth spurt means your body is changing more and more into a grown-up. You will know when this happens. Your baby face will slowly look more adult-like. Your clothes and shoes will feel tighter. You will gain weight. You will get stronger as your muscles grow bigger.
The peak growth spurt for boys usually happens about two years after puberty starts. When it does, you will have fuller, broader shoulders and bigger feet and hands. One sign that a growth spurt is starting is a rapid increase in shoe size.
A kid going through puberty usually grows about 4 inches taller every year until he turns 17. After age 17, your height probably won't change. About 25% of a person's lifetime growth in height happens during puberty.
How tall you become usually depends on how tall your parents are. If you have tall parents, you'll probably be taller than average. If your parents are short, chances are, you will be, too.
A growth spurt can also make you feel hungry all the time. That's normal. A growing body needs fuel. Just make sure you eat healthy foods and snacks.
When Will I Grow Body Hair?
You'll see hair first between your legs near your private parts. This is called the pubic area. Soon, you'll spot hair on your legs, underarms, and chest. As you continue through puberty, this hair will get thicker and curlier.
If you still have baby-smooth skin on your face, don't worry. Facial hair grows later on in puberty. But soon enough you'll have a hairy "5 o'clock shadow" and will be asking to borrow your dad's electric razor.
