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, while BDSM encompasses a range of activities involving bondage, dominance, submission, and sadomasochism. Role-playing involves acting out specific scenarios or fantasies, while voyeurism is the act of watching others engage in sexual activities without their knowledge or consent. People engage in these fetishes through communication, consent, and exploration with willing partners.
