Women get periods.
But a lot of people get bad back pain, which doesnt dissapear after 5 days. People live in wheelchairs. Some are disabled.
Of course, some women have these things ontop of periods too.
Then again, some contraceptive shots can kill periods for some women. Being a skinny runner and you might get minimal period
Then again, some males have sexual disfunction. That stuff is rough and doesnt just happen 5 days a month
Some guys have to worry about penis size eeeek. Sure, some women might feel pressure about their bodies, breast size etc, but nothing surely can compare to how much is made (by ourselves and females) of sexual performance.
