The following is based on a phone conversation with a male friend:
HIM: So what are you doing?
ME: Lying on the couch resting my uterus.
HIM: You know what? This conversation is over...
*smooches...wondering why dudes get so squeamish about menstruation*
it's a natural, biological function that every woman, EVEN YOUR MOMMA, goes through. accept it and move on!
