We are talking about someone else's suffering. If men experienced menstruation perhaps they would learn something.
I can just imagine any man I have ever met spending days each month depressed, doubled over, vomiting, and bleeding into their shoes and tripping merrily through life like it was a joy to menstruate.
I wish you could try to see from a sufferer's point of view rather than spewing venom, but obviously that is not going to happen. I hope you are kinder to the people in your actual life.
