There are changes that happen, but they occur slowly over a period of time rather than as a single event. There are certain stages of development that boys go through when developing secondary sex characteristics. Here is a brief overview of the changes that happen:. In boys, the first puberty change is the enlargement of the scrotum and testes.
At this point, the penis does not enlarge. The first growth of pubic hair produces long, soft hair that is only in a small area around the genitals.
The pubic hair eventually looks like adult hair, but in a smaller area. It may spread to the thighs and sometimes up the stomach. Body size will increase. Sometimes the feet, arms, legs, and hands may grow faster than the rest of the body.
This may cause a teen to feel clumsy. Some boys may get some swelling in the breast area. This is a result of the hormonal changes that are happening. This is common among teenage boys and is often a short-term or temporary condition. Talk with your son's healthcare provider if this is a concern. Voice changes may happen, as the voice gets deeper. Sometimes the voice may "crack" during this time. This is a temporary condition and will improve over time. Hair will start to grow in the genital area.
Boys will also have hair growth on their face, under their arms, and on their legs. As the puberty hormones increase, teens may have an increase in oily skin and sweating.

Acne is caused by glands in the skin that produce a natural oil called sebum. Puberty hormones make the glands produce extra sebum, which can clog the pores.
Washing gently with water and mild soap can get rid of excess sebum and help reduce breakouts. Over-the-counter and prescription medications are available for more severe cases of acne. Your family doctor can recommend a dermatologist a doctor who specializes in treating the skin if basic skin care and OTC medications don't keep acne under control.
Kids who once associated bath time with play need to learn to wash regularly and to apply deodorant or antiperspirant. A teen who's learning to shave will need to learn how to keep a razor clean, to throw a disposable one away before it becomes dull and ineffective, and to not share it with others.
Boys, capable of having erections since infancy, can now experience ejaculation. Usually, this first happens between the ages of 11 and 15, either spontaneously in connection with sexual fantasies, during masturbation, or as a nocturnal emission also called a wet dream. If he doesn't know about wet dreams before he has one, a boy may think he has urinated accidentally or that something has gone wrong with his body.

As far as the myths and beliefs about masturbation: No, it won't cause kids to grow hair on their hands, become infertile, go blind, or develop new emotional problems.
A small number of kids and teens with already existing emotional problems may become preoccupied with masturbation — just as they may become overly occupied with other behaviors or thoughts. Constant or obsessive masturbation may be a sign of anxiety or other emotional problem. But, other than that, masturbation is generally considered by doctors to be a common form of normal sexual self-exploration. Although some preteens and teens may choose to masturbate, others may not.
Because masturbation is often considered a private topic, many kids might feel too embarrassed to talk about it because they're concerned that their parents will be angry or disappointed with them.
