feminism's critique of body image, beauty ideals, etc.
You might find looking at some articles, blogs or books that deal with body image, sexuality and so on interesting. Feminism in all of its variations deals extensively with these issues - and not just from women's point of view although that is a focus of course.
One place to start is Naomi Wolf's 'The Beauty Myth'. Not everyone agrees with Wolf but she does a good job in delineating the current situation in my opinion.
