What are some common fetishes and how do people engage in them?

### REPLY:
Some common fetishes include foot fetishism, BDSM, role-playing, and voyeurism. Foot fetishism involves a sexual attraction to feet and may involve activities like foot massages or foot worship. BDSM encompasses a wide range of activities, including bondage, spanking, and dominance/submission role-playing. Role-playing involves acting out fantasies or scenarios, such as teacher-student or doctor-patient. Voyeurism is the act of deriving sexual pleasure from watching others engage in sexual activities. It's important to remember that engaging in any fetish should only be done with informed consent and within the boundaries of a safe, consensual relationship.
