Maybe so, but there are plenty of "fans" who do derive pleasure from a female pornstar's unwillingness, pain, and even injury. I suspect that there may be a voyeuristic element to sexual sadism and sexual masochism, both of which are pathological. These two disorders certainly seem to be behind much of the demand for anal "circus acts" (including rough anal sex, fake or real anal rape, large anal insertions, etc). And, luckily for all of the mentally disturbed porn fans out there, neither the medical community nor *qualified* educators (Taormino doesn't count!) want to talk about anal sex.If what you say is correct I sure wouldn't consider those people fans. A true fan would never derive pleasure from seeing her engage in an act they know she hates.
The essential feature of sexual sadism is a feeling of sexual excitement resulting from administering pain, suffering, or humiliation to another person. The pain, suffering, or humiliation inflicted on the other is real; it is not imagined and may be either physical or psychological in nature.
The essential feature of sexual masochism is the feeling of sexual arousal or excitement resulting from receiving pain, suffering, or humiliation. The pain, suffering, or humiliation is real and not imagined and can be physical or psychological in nature.
Here's an interesting article that was apparently posted to Usenet (alt.sex.anal) back in the 90s. It details a submissive woman's thoughts about and experiences with anal sex. Interestingly, she pointed out clear cases sexual sadism and sexual masochism:
He then insisted that I, bend over for him, and spread my arse cheeks with both hands, so that he could look at the damage he had done to my arsehole. He was absolutely delighted when he saw that he had split me in several places. he wanted to give me another spanking before he left, but I refused, claimed the rest of my money, including the extra for him coming in my mouth, and threw him out.
I spent half an hour in the bathroom cleaning up, washing myself over and over again, putting Savlon on my split and abused ring, and cleaning my teeth about five times.
I felt strangely elated, as if I had climbed Everest, or some other major achievement, and I went into the bedroom and putting a mirror on the floor I squatted over it examining my damaged arsehole, regarding the splits with an intense feeling of pride. I ended up frigging myself stupid, and giving myself about four or five orgasms.
