Most teens don't want to talk about masturbation. Even though it might feel embarrassing to talk about it, many teens do it.
In fact, more than half of 14-year-old boys admit they've masturbated. That means at least one out of every two of your guy friends has done it -- even if they won't admit to it. (About half of the girls in your class are doing it, too.)
Here are some honest answers to questions you might have been too embarrassed to ask about masturbation.
But there is something you can do to protect yourself. It's called a testicle self-exam.
If you do one every month, your chances of finding cancer early are very good. When that happens, the cancer is a lot easier to treat. That means your chances of survival are very good.
What Is Testicular Cancer?
Your testicles, what you more likely call balls, are part of the male reproductive system. They are the two balls that hang in the sac, known as the scrotum, under your penis.
The testicles are the part of your body that produce sperm. They also produce a male hormone called testosterone that gives your body many of its male characteristics -- like a deep voice or hair on the face.
With testicular cancer, abnormal cells in the testicles divide uncontrollably and form a cancerous tumor. If the cancer isn't treated, those cells can break off and spread to other parts of the body.
Testicular cancer is not particularly common. There are about 8,300 new cases a year. And about 350 men die each year from this cancer. But while some men are more likely to get it than others, it's possible for any young man to get the disease.
Why You Should Consider Giving Yourself a Self-Exam Each Month
Unless you have certain risk factors, such as a brother or father who has or had testicular cancer, the American Cancer Society (ACS) says there aren't enough studies to make monthly exams a recommendation.
But because the cancer is so easy to treat when found early, even the ACS says many doctors recommend the exam. And besides finding cancer early, the exam can help you find other problems that may need to be treated.
