Well doc, boys don't know shit about period pain. For one, they haven't experienced it biologically. Second, the family dynamics in Asia especially keeps the boys away from such natural events. Mom's and sisters don't talk about them, the sanitary pads are always hidden, the stained panties washed and hidden out of sight. Why? If you women are ashamed of what's a normal biological event, if you don't have the courage to explain to the boyfolks or menfolk what's happening, it's frustrating..
