I'm very surprised to mainly only find studies on impact/effect of pornography on humans with almost none study on topology/dynamics/evolution of the object itself. Does some of you have some references in mind that dig in that direction ? (If I manage to arrange a dataset out of available data on public website, I would be glad to share it, let me know if you're interested.) Thanks for your help, All best, Antoine http://mazier.es/
