A clear and also common example of male privilege that you may not think about could present itself in the following scenario.
guy: *hits on girl
girl: “Sorry, not interested”
guy: *continues to hit on girl
girl: “Seriously dude, not interested”
guy: *..still trying
girl: “I have a boyfriend”
guy: *stops relentless flirtation efforts.
While not ever guy will simply stop unwanted advances towards a woman because she has a boyfriend, that is exactly what many do. Thankfully the unwanted advances may stop, but what bothers me is the reason they stop. It is not out of respect for the female’s lack of sexual/romantic interest in the guy, but rather the male to male respect that would create boundary lines.
