To live in a culture in which women are routinely naked where men aren't is to learn inequality in little ways all day long. So even if we agree that sexual imagery is in fact a language, it is clearly one that is already heavily edited to protect men's sexual - and hence social - confidence while undermining that of women.
Culture stereotypes women to fit the myth by flattening the feminine into beauty-without-intelligence or intelligence-without-beauty; women are allowed a mind or a body but not both.
