That's on the individual.
If you just sit at home all day and not want to do things, then yes you are lazy. If you don't want to become lazy, be active!
Well we do get lazy sometimes and for me its school and it's not often but I will sit there and do no work... The hormones released during puberty do have an affect on teenagers. They want to sleep longer than before so you could say they get lazy.
That has more to do with upbringing and personality than with gender. Some boys are lazier than some girls, but some girls are lazier than some boys.
yes ,they do but not all at the same time.
Usually the boys hit puberty at the ages of 13. It depends on the child on how to console him.
Boys develop and mature at different rates. Even if your friends have started to mature before you, don't worry; it's totally natural and there is nothing to be concerned about.Although the average age at which boys start puberty is 12 to 13 it can start at anywhere from 9 right up until 16. Puberty lasts around 5-6 years on average for boys. Most boys have finished puberty by the time they are 18-20.There are many factors involved and remember everyone is different.See the related question below for more information.
It varies between the age of 10-16 or17
The average age for girls to begin puberty is 11, while for boys the average age is 12. But it's different for everyone, so don't worry if your child reaches puberty before or after their friends. It's completely normal for puberty to begin at any point from the ages of 8 to 14.
Some young boys do until they hit puberty & can't stop thinking about how bad they want your body.
Different people enter puberty at different ages. Girls sometimes enter puberty at 8 years of age, and boys sometimes enter puberty at age 10. Of course, it is normal to enter puberty 8 to 10 years after those ages, too.
One of the first indicators is hair starting to grow on the penis.
Boys can get erections at any age, and in fact it has been cited that babies still in the womb get erections. However, up until puberty, this is usually for different reasons. Before puberty, young boys can get erections due to friction from clothes, or from "adjusting" themselves. However, once they hit puberty, sexual desire and arousal will influence erections,
It's perfectly normal. Puberty starts at different times for everybody. Most girls hit puberty around 11, but it takes longer for boys.
