Girls get periods and they have it so that while ovulating (getting her period) and has sex she can become pregnant. Men don't have periods because they carry sperm to help get a woman pregnant. And you know that men can't have babys.

Girls get periods as part of their menstrual cycle which prepares the body for pregnancy. When pregnancy doesn't occur, the uterine lining sheds, resulting in menstruation. Guys do not have periods because they do not have a uterus or the reproductive organs necessary for menstruation.

If girls have periods what do guys have?

Guys do not have periods because they do not have a menstrual cycle. Guys do not experience the same hormonal changes and shedding of the uterine lining that occurs during a menstrual cycle in females.


Do guys have periods?

No, guys do not have periods. Menstruation is a biological process that occurs in individuals with female reproductive systems.


Why are guys typically taller than girls?

Guys are typically taller than girls due to genetic factors, specifically the presence of the Y chromosome in males which tends to promote greater growth and height compared to females. Additionally, hormones such as testosterone play a role in the development of male characteristics, including height.


What do girls experience in response to sexual arousal, in comparison to the physical reaction of guys getting boners?

Girls may experience increased blood flow to the genitals, lubrication, and swelling of the clitoris in response to sexual arousal. This is different from the physical reaction of guys getting erections, which involves increased blood flow to the penis, causing it to become erect.


Why does your period have to happen to girls and not guys?

Periods are a natural process that happens to girls because they have a uterus and eggs that can be fertilized. During a menstrual cycle, the uterine lining thickens in preparation for pregnancy, and if fertilization doesn't occur, the lining sheds, leading to menstruation. Guys do not have the reproductive anatomy necessary for menstruation.
