The average age would be thirteen however menstruation is different for every female.
yes, if you are a girl, you menstruate.
No, not every female gets her period. If talking exclusively of those who are biologically female there are those who don't have the anatomy to menstruate or their bodies don't produce the hormones needed to have a menstrual cycle. Pre-pubescent girls don't menstruate and women past menopause don't menstruate, also women who are pregnant won't menstruate during pregnancy (sometimes for longer if they breastfeed), and women who have a hysterectomy to remove the uterus.

Thankfully, female guinea pig don't menstruate.
No women fail to menstruate. It comes naturally.
Firstly, some men menstruated too - anyone with a vagina, uterus, and ovaries can menstruate - it's not just girls and women who have these body parts. Females menstruate because we are the ones who get pregnant, the body prepares for pregnancy and if we don't fall pregnant the uterus lining sheds so it can renew again next cycle ready for the next possible pregnancy.
No, not all girls get periods, also for the record some boys do get periods.There are lots of reasons why some girls don't get periods, some girls don't have the reproductive organs needed to menstruate whereas with others there may be more complex medical reasons.
