Andrea Dworkin explains in 'Pornography' that women are seen as objects used only to please men. The word pornography comes from greeks words: porne and graphos. Porne means least regarded and least protected of all women. Graphos means writing, etching, or drawing. She is trying to say that pornography means the lowest regarded women and the art of using them. Thus meaning, the use of sex. Anne Koedt explains in 'The Myth of the Vaginal Orgasm' that sex is only to please men, and women that do not climax during 'regular' vaginal sex are seen as inadequate and not normal. She argues that a woman only climaxes from clitoral stimulation.
Each author agrees that men are still seen as superior during sex, and this again follows the system of patriarchy. Although, the authors are arguing different points. Dworkin talks about the disrespectful display of women in porn, while Koedt elaborates on the fact that sex is seen only to pleasure men. Men know what pleases women, yet they still choose to do what pleases themselves. Thus, women are defined in terms of a man's pleasure. This is where Koedt and Dworkin are very similar.
Each author brings up in depth arguments, yet each differ. Dworkin takes it to a level beyond rational thinking, where as Koedt reevaluates attention and interworkings of sex.
