Nothing; just be patient and let nature take its course.
Puberty does not begin at the same time for everyone. Girls on average begin puberty a year before boys.
A nine year old may get her period, but I'm not sure what you mean by sooner - sooner than what? A woman will only start to menstruate when she is due to menstruate, the menstrual cycle cannot be sped up or puberty sped-up to menstruate for the first time before you're ready.
There are 2 things that might explain this: 1/ You will end puberty sooner than your friends. 2/ You start puberty earlier than your friends.
Boys can experience orgasms at most any age (even when they're infants), but they won't ejaculate (cum, or come) until they reach puberty - which usually happens between the ages of 11-15. Some reach puberty a year or two earlier, and some don't reach puberty until they're a couple of years older. If a boy has not reached puberty or is unable to ejaculate by age 17, it is usually recommended that he sees his family doctor to make sure that there is not some other problem.
Masturbation is completely normal for boys and girls once they reach Puberty, as long as they do it in private.
A filly enters puberty in the spring because it's brought on by photoperiod, but which spring the enters it in depends on her calender month of birth and her own individual biology. Usually about 50% start puberty in their first spring, as yearlings, and another 50% in their second spring. It's very rare you'll find an individual entering puberty in her third year.
That's perfectly average for an 11 year old. You won't see any major growth in the genitals until you reach puberty.
Cattle will begin puberty as young as 4 to 5 months of age and reach sexual maturity at about 1 year or 12 months of age. Naturally this depends on the breed and the genetics of the cattle herd itself. Some breeds will have bulls and heifers beginning puberty at 8 to 9 months, or even later, at 10 to 12 months. Such animals may not reach sexual maturity until 15 to 20 months of age, respectively, or more.Note that age of puberty to rate of maturity is like comparing apples to oranges: they are two different traits, one is not affected by the other.The average at which cattle reach puberty is about 11 to 13 months. Generally, a heifer is able to breed successfully at about 18 months. A bull can successfully breed at about the same age.
Medically there is no such thing as "normal". Your body will begin puberty when it is ready. usually this is at 11 years old. However due to biological and possibly genetic changes in future generations (probably evolution?) scientists have noted that children are starting to reach puberty quicker, particularly girls. For example, millions of girls in 2012 started their puberty at the age of 9.
There is NO magic spell. You have to let nature takes it course. The eight you reach later in puberty is the one set out in your genes.
No, it is not. The average age is 12 years in boys. Most probably you r not going through puberty. Precocious Puberty (early puberty) is rare but not unheard of so if your child has the signs of puberty at 8 years old then you should take them to the doctor to be checked.
it certainly depepnds on how fast you grow and reach puberty, some children have underarm hair when they are eleven so it is certainly natural
