### REPLY:
There are several common fetishes that people engage in, such as BDSM, foot fetishism, role-play, and voyeurism. BDSM involves various acts of bondage, dominance, submission, and sadomasochism. Foot fetishism is a sexual attraction to feet, often involving foot worship or other foot-related activities. Role-play involves acting out specific scenarios or fantasies, such as teacher-student or doctor-patient role-play. Voyeurism is the act of gaining sexual pleasure from watching others engage in sexual activities, often through peeping or voyeuristic scenarios.
