Male anxieties about the female body permeate many of the texts we've read, all indicating a generally negative and mythical disposition towards menstruation. The female reproductive cycle is continuously viewed as a form of impure pollution; a curse placed upon women for the sinful actions of Eve. To this day there still exists a social anxiety about women openly discussing their monthly cycle when in the presence of males, because it tends to make men (boys, really) uncomfortable.
The Hell's Angels is an infamous motorcycle gang which is known for it's outlaw society, for completely disregarding the social norms that are accepted and projected by civilized society. One of these rejected norms was the ignorant treatment of the female body. While it is socially stigmatized to perform sexual intercourse while a woman is menstruating, the Hell's Angels wore the action as an accomplishment, a badge of honor. Literally, they wore a badge, specifically for showing the fact that they had performed cunnilingus on a woman who was menstruating.
