Sexuality/Sensuality in Porter and O'Connor

I have started researching various critical essays/articles for this week but I still have a lot to do. I am thinking about writing on how sexuality/sensuality is expressed in various stories. I am also interested in how different female characters are sexualized. For example the protagonist in "Flowering Judas," the Maria Rosa in "Maria Concepcion," Hulga in "Good Country People," one of the German daughters in "Holiday", and Amy in "Old Mortality". I am wondering whether or not to do a comparison of these concepts as portrayed by Porter versus O'Connor. I think that Porter takes a much more sensual approach in these stories, while O'Conner seems to distort sexuality. I am interested in the lack of sexuality in most of the short stories. The two authors seem much more interested with violence than they do with senusuality/sexuality, which I find strange because of their experience with different men. I have found two websites that list various criticism on the two authors and I have made a list of some that might relate to my topic. I will need to research if the absense is due to sexuality being a taboo topic at the time. Also, another direction that I might be headed in is the relation of sensuality to individuals that are considered to be the Other (ie: Mexico stories/German daughter/physically handicapped). As I said in class, I need to head to the library to seek out the actual essays and to do more research.
