What are some common fetishes and their characteristics?

### REPLY:
Some common fetishes include foot fetishism, BDSM, role-playing, and voyeurism. Foot fetishism involves a sexual attraction to feet and may involve activities such as foot massages, worship, or trampling. BDSM stands for bondage, domination, submission, and sadism, and includes various forms of power exchange and kinky activities. Role-playing involves pretending to be someone else in a sexual scenario, such as a teacher and student or a doctor and patient. Voyeurism is the act of gaining sexual pleasure from watching others engage in sexual activities without their knowledge or consent.
