I'm not sure that if men could menstruate they would make it seem as if they were all tough, and act as if were awesome that they shed blood, because honestly, every time I've seen a grown man remotely sick, they are the biggest babies about it. Groaning, moaning, "not able to do anything," and sleeping. They just become worthless. So if men could menstruate I do not think they would handle it well at all, and women would get frustrated at the fact that their husbands have become their "sons" for a few days each month.
