Dealing With Embarrassing Body Changes

On the way to manhood, your body is going to do a lot of things that you really, really wish it wouldn’t. Pimples will pop up everywhere, and so will hair. You’ll drip sweat and you will stink. You’ll get erections when you least expect – or want – them. Sound bad? Sure. But remember these four things: Every boy goes through this (though not in exactly the same way or on the same schedule). It is normal (no matter how hard that is to believe). None of it will go on forever (even though...

When does the penis grow?

Your penis grows longer and wider during puberty. That's the time major changes occur in the body that make you look more like a man and less like a child. Most guys start puberty between ages 10 and 14.

But, puberty happens at different times for everyone. You may have a penis that's grown to its full size as early as age 13 or as late as age 18.

When does a penis stop growing?

Your penis stops growing when you finish puberty. Exactly when that happens, though, varies from person to person. Everyone develops at a different pace. You may take longer than your friends or less time than them to finish puberty. But by 16, your body and its parts should be close to your adult size.

Is my penis size normal?

There is no such thing as a "normal" penis size. 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.

Can I change my penis size?

No. You can't change the size of your penis. Despite what you may hear, no exercises, vitamins, or diets can change the size of your penis or make it grow faster.

What is a morning erection?

An erection is when your penis fills with blood and becomes hard. A morning erection is an erection you wake up with in the morning.

Morning erections are very common. In fact, most guys have about three to five erections each night while they sleep. They just don't know it.

What is a wet dream?

A wet dream is when you ejaculate (release semen from your penis) in your sleep and wake up wet. Wet dreams often occur from having sexual dreams. Sometimes, though, they just happen. Wet dreams are a normal part of puberty. Usually, they stop as you get older.

How can I prevent having an involuntary erection?

Unfortunately, you can't. During puberty, erections just happen. There isn't much you can do to stop them. Even thinking of the most non-sexy thing you can imagine won't help. But, over time, involuntary erections will become less frequent.

What is masturbation?

When you masturbate, you release sexual tension. You'll have what's called an ejaculation. Ejaculation is the release of semen from your penis. Semen is made up of fluid and sperm.

Many guys masturbate. In fact, one study of 15- and 16-year-olds found that 75% of boys said they masturbated.

There are many myths about masturbation. For example, some people say it will stunt your growth. But there is nothing wrong with doing it as long as it doesn't become a constant desire or get in the way of other things you want or need to do.
