This is a no brainer. The govt can't control the sex lives of their people, however, If I play music at 47dbs late at night for a long period of time for many nights or any nights, thats going to piss a lot of people off.  The issue isn't that they are having sex, its how much noise are they making.  It doesn't matter if its sex music, or chanting or construction, if its loud, disruptive, prolonged and for many nights or every night then the govt can say you are disturbing the peace/breaking the noise ordinance and then take action like they would for me if I was playing my music too loud, too late and everynight.
