In magazines, what stands out in my mind is the pictures, more than the text. I would go purchase a mens magazine, i.e. GQ, playboy, maxim, car magazine, or something along those lines, and a womens magazine, cosmpolitan, elle, preferrably not tabloid. Next I would start to look at what the pictures are saying about a given gender. I.E in the mens magazing what is the picture saying about how women should be, and what does the pictures of a half naked women say about the gender role of men. just an idea
