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

### REPLY:
Some common fetishes include BDSM, foot fetish, role-playing, and voyeurism. BDSM involves various power dynamics and activities such as bondage, dominance, submission, and sadomasochism. Foot fetish is a sexual attraction to feet and often involves foot worship or foot massages. Role-playing involves acting out specific scenarios or fantasies with a partner, such as teacher-student or doctor-patient role play. Voyeurism is the act of gaining sexual pleasure from watching others engage in sexual activities. It's important to note that engaging in any fetish activity should always be consensual, respectful, and within legal boundaries.
