How about really doing something to them if you actually catch them in the act? Frankly, while I think it’s disgusting as all get out, I find it difficult to imagine that signaling someone that you want sex is illegal. Heck, you can toss the F word out in public and I don’t think they can arrest you for that.

I don’t want my son to “catch them in the act” the next time we fly through that Airport.
And I don’t want them witnessing heterosexual reproductive behavior in public places EITHER.
There are reasons Plato referred to uncontrolled sexual urges as the “Tyranny of the Appetite”.
