Yes, actually, some do. Girls go into puberty at various times but the average age is between 9 and 14. It's perfectly normal for an eleven year old to wear a bra, but not all of them do.
Unsurprisingly, the average age of an eleven year old is eleven years old.

Yes it is possible. The normal range over which boys start puberty is from 9 years of age until the late teens. On average most boys start puberty around 12 or 13 years of age. Puberty in boys generally lasts for around 6 years. The testes begin to grow early in puberty and it is quite normal for a boy to begin to produce sperm a year or so after begining puberty. So if a boy started puberty at age 9 or 10 he could be producing sperm by the time he was 11 years old.
The age of puberty in females in 11-12 years of age. Though there may be 1-2 year +- change.
For males, from the age 13-16 you will be starting puberty
Everybody hits puberty at a different age. 7-12 is the normal range for beginning puberty.
Children grow at different rates, especially boys. It is normal, for example, for an 11 year old boy to be shorter than some girls his age.
The usual age at which puberty starts is 12 for boys. So yes, you may be having puberty.
Usually puberty starts at the age of 12-13 in boys. So it may be okay if you talk a year later.
Sperm is produced when a boy has reached puberty. The average age to hit puberty is around 12-13-years-old. It would be very unlikely for a boy that age to have hit puberty. I have not heard of it.
