Physics teaches us, at least by suggestion, of what can happen in the social, the psychological, and spiritual world we live in too. No act, even under the greatest cover, in the darkest room, goes on without affect on all of us. Not only at the time of the act, but also the actors in that act carry the results -- the fruit, the scent, the echo -- out of that private space with them.
You're creating a rather bazaar construct, trying to attach physics to ones' privacy within the confines of their own home (which is where this act took place).

Well, I don't think Physics teaches us that. Socialogy might. But you have to ask, is the effect noticable and is it significant and is it detrimental?
A line probably needs to be drawn with regard to sexual behavior but that line ought not to cross the threshold of ones' home.
