If you were unfortunate to wander anywhere near the arts and humanities from 1988 to today, but especially from roughly 1993 to 2002, you probably got your ear talked off at some point about how the patriarchy socially constructs borders or boundaries of female sexuality -- what's permissible and what isn't -- and actively polices them -- or makes sure that females don't get out of line.
Only a bunch of haggard old feminist dingbats, and men who haven't been around young girls in decades, could believe such a thing. For a quick reality check, here's a YouTube video of two 8th graders. One is more sexually aggressive than the other, and for this her friend crucifies her in that girly way of teasing her while smiling. It's girls, not the patriarchy, who do this to each other. Also note that these girls are still going through puberty, yet their merciless teasing and policing instincts are fully developed. So much for the social construction part of it!
See here for an academic lit review that comes to the same conclusion.
