I was at one time a fanatical fan of Nina in her early days in adult, when she was still more of a Red Diaper Leftist. She has evolved more into a classic liberal in her later years, and we have had a separation of ways due totally to eff ups of my doing, but she still remains one of my Muses.
She has written a bunch of contributions to sex worker and adult industry activism. Google "Sex Work: Readings By Women In The Adult Industry" for one example.
