Funny… I’ve seen onlyforhim4ever’s problem from the other side. I’m not affiliated with law enforcement, but I did end up interrupting something… I was walking in a park outside of Bordeaux, France when I heard a woman screaming softly nearby. I pulled a knife and jumped a low stone wall, ready for violence… to find a young couple in what was obviously a BDSM ‘scene’. I apologized to the startled couple, confirmed consensuality, and went on my way. Not an experience I would recommend, for any of the involved parties…

Anyway, it can be very difficult to hear the difference between 'Ouch this is fun!' and 'help me!'. While this does not seem to be the issue in onlyforhim4ever’s case, one should play at a time and a place so as to not alarm passers-by. It should not be loud enough that neighbors get concerned, one’s children should not ‘discover’ it at an unacceptable age, and one should avoid the ‘vanilla’ public. Wear a gag; hire a sitter; rent a hotel room. Still, it is one thing for herMaster4ever’s roommate to be bothered by the noise, and quite another for him to call the cops rather than talk to herMaster4ever about it.
