I was going to post this in another thread ("What is one type of genre you try and avoid for writing?") but figured this was the best place to post this. I should mention that I don't read erotica, which is why I'm asking these questions. I'm unclear as to the purpose of erotica. The way I understand it, erotica is like porn. Not many people study it seriously, and it's only used as a means of sexual gratification (I could be wrong about this). So is it meant to simply "entertain"? Is it meant to provide social commentary in some way? Can it be seriously discussed and studied (either in a casual or academic setting)? I honestly have no clue and would love to hear answers from others.
