Puberty
There are also changes that happen in the brain. Boys and girls may think about sex more. While children of any age explore, touch and play with their sex organs from time to time, all boys and most girls going through puberty do this a lot. This is called masturbation and is a totally normal and healthy thing to do. Boys and girls going through puberty may question their sexual orientation, meaning they find they are more attracted to the people of the opposite sex, or to people of their own sex, or to both, or their sexual feelings may be fluid (changing) and complicated, often called being queer. People going through puberty often have strong emotions or feelings about many things. Other changes in the brain may make it harder learn a new language the way they learned language(s) when they were young. This change involves something called brain plasticity. It means that children's brains are more flexible in learning.
