Your fetishes, your sexuality, reveal who you are. The problem is that it's not affected, it is really you, it's what you do for pleasure, what you truly want to do. It shows a side of yourself that could easily be disgusting to other people. It might gross people out. It's like the skid-marks on your underwear or blowing your nose or merely appearing naked. It makes you vulnerable to scorn. This is why viewing “adult material”, for most, is private, especially if they like minorities or homosexuality or something that nobody they know finds appealing. It's secret and personal. This gives the people who make adult entertainment, who make the things that are shameful powerful in society, power. You make erotica with submissive men, or fat women, or grannies, you become powerful.
Anything that can destroy a reputation or ruin a relationship is powerful because it thrives only as the result of a compulsion, something that goes beyond options and what people want to do. If you can tap into the thing that people need to consume and you can control your product, meaning who has it, then you will make money. It becomes like crack or heroin.
Cater to the low, dark side, the side that wants revenge or is fascinated by stories of serial-killing and rape and perversion. You make any story into a soap opera with clichéd twists and contrived circumstances that are simple enough for anybody to understand and yet too complicated for the people on film to figure out and solve until the requisite number of episodes.
Everybody has a dark, stupid side, the part of themselves that longs for the lurid. Usually, it's the same side. Intelligent women whose identity is in their ability to think, they long for the release of ridiculous romance. Women who claim to respect themselves and embody feminist or wholesome family values, they long to do away with discretion and indulge themselves in the lifestyle of the "low woman," the indiscriminate slut. People and the rules they crave to violate offer a market to the intelligent entrepreneur. Everybody longs for their own forbidden fruit, longs to jump the fence eat from the greener pasture, you just have to come up with a way to satisfy it and sell it to them without anybody finding out.
