From Wikipedia
Menstruation is the shedding of the uterine lining (endometrium). It occurs on a regular basis in reproductive-age females of certain mammal species.
The answer to your question is the while a girl has a uterus, and therefore a uterine lining which can be shed every month, boys do not. The uterus is where the baby is grown before it is born.
because boys don't have uterus's to shed. they cant have periods with no uterus es
No.
Yes, some boys will menstruate.Some men have a vagina, uterus, and ovaries so will menstruate just like cis women do. Remember that not all men have a penis, and some men have a vagina.Cis men do not have periods or "that time of the month" - menstruation is a specific function, it is not just women being moody and getting menstrual cramps. It's sexist to suggest that women's menstruation is just their being moody and cramping, neither of these are a normal part of menstruation but part of a social construct around menstruation or a result of hormonal imbalance.
i have had the same problem for about 4 years now, last time i wasn't on my periods for 3 months, i told my doctor and she said it is normal to be like that... i recommend you to see your doctor about this, it can be something serious
