Interesting. I really like when sexworkers write about SW and then other SWers might find the writings and then write about SW themselves. I love that the voice of SWers is becoming stronger in this way.
I'm writing a paper too! I'm coming from a fine art perspective so it may be different to how you approach it but I've been able to apply some of the feminist discourse about porn to my theories about webcam modelling. My paper is about performing sexuality within patriarchal structures.
I'm sure you've done a good amount of research but here's what I've particularly enjoyed reading. Worth putting down for anyone else who might be interested in reading more about this kind of stuff:
This book has been a great resource for me to intro me into the idea of third wave feminism and girlie feminism. In particular chapter 11. BUST-ing the Third Wave: Barbies, Blowjobs and Girlie Feminism.
Mainstreaming Sex: The sexualisation of Western Culture. Feona Attwood.
Lots of interesting things on
