Erections happen when guys fantasize and think about sexual things or sometimes for no reason at all. They may experience something called nocturnal emissions or wet dreams , when the penis becomes erect while a guy is sleeping and he ejaculates. When a guy ejaculates, semen comes out of the penis — semen is a fluid that contains sperm. That's why they're called wet dreams — they happen when you're sleeping and your underwear or the bed might be a little wet when you wake up.
Wet dreams become less frequent as guys progress through puberty, and they eventually stop. Guys will also notice that their voices may "crack" and eventually get deeper. Just as those hormones create changes in the way your body looks on the outside, they also create changes on the inside. While your body is adjusting to all the new hormones, so is your mind. During puberty, you might feel confused or have strong emotions that you've never experienced before. You may feel anxious about how your changing body looks.
You might feel overly sensitive or become easily upset. Some teens lose their tempers more than usual and get angry at their friends or families. Sometimes it can be difficult to deal with all of these new emotions. Usually people aren't trying to hurt your feelings or upset you on purpose. It might not be your family or friends making you angry — it might be your new "puberty brain" trying to adjust.
And while the adjustment can feel difficult in the beginning, it will gradually become easier. It can help to talk to someone and share the burden of how you're feeling — a friend or, even better, a parent, older sibling, or adult who's gone through it all before. You might have new, confusing feelings about sex — and lot of questions. The adult hormones estrogen and testosterone are signals that your body is giving you new responsibilities, like the ability to create a child. That's why it's important to get all your questions answered.
It's easy to feel embarrassed or anxious when talking about sex, but you need to be sure you have all the right information. Some teens can talk to their parents about sex and get all their questions answered. But if you feel funny talking to your parents about sex, there are many other people to talk to, like your doctor , a school nurse, a teacher, a school counselor, or another adult you feel comfortable talking with.
People are all a little different from one another, so it makes sense that they don't all develop in the same way. No two people are at exactly the same stage as they go through puberty, and everyone changes at his or her own pace. Some of your friends may be getting curves, whereas you don't have any yet.
Maybe your best friend's voice has changed, and you think you still sound like a kid with a high, squeaky voice. Or maybe you're sick of being the tallest girl in your class or the only boy who has to shave.
But eventually everyone catches up, and the differences between you and your friends will even out. It's also good to keep in mind that there is no right or wrong way to look. That's what makes us human — we all have qualities that make us unique, on the inside and the outside. Reviewed by: Steven Dowshen, MD.
