I believe gp was referring to places where sex is already forbidden by a property owner such as classrooms and offices, where if someone walks in on you having sex, you're the weird one because you shouldn't be having sex there, someone could walk in on you, there's no expectation of privacy. It's their property and they're paying you to be there temporarily to provide a service. > landlords (even university campuses) have no business meddling in 'unwanted consensual activities' Agreed, and I think GP would as well. Dorms are different. That's your domicile, the relationship with a university is that of a landlord/tenant. You're paying for a place to sleep and live. There's an expectation of privacy. If you walk into someone's dorm while they're having sex, why the hell are you barging into someone's room? That being said seeing a sex detector hanging from the ceiling would make me sad.
