This is somewhat along the same lines as [my other question](https://law.stackexchange.com/questions/62386/can-the-federal-government-outlaw-sex). I would like to learn more about the constitutional boundaries on the US Congress to regulate sexual mores and/or sexual customs.

I assume the government's power to regulate forms of worship is so limited that it would not allow it to regulate propositioning for sex in places of worship.

The federal government clearly can outlaw *certain forms* of propositioning for sex (as it has done with sexual harassment laws) in places of business.

The government can outlaw sex in public as a public nuisance. In fact, merely exposing oneself in public can lead to a requirement to register, as a sex offender, for many years after serving a prison sentence. So this form of lewd propositioning is clearly illegal.

The government can treat certain utterances as intimidation even if they don't contain a direct threat (e.g., protests at abortion clinics). So the government can at least attempt to extend this theory to propositioning people on the street directly.

Can it be extended to private residences for reasons (for example) of public safety? Or are there no constitutionally-accepted reasons why the government can extend it to private residences?

Again, I am not looking for answer telling me that the government *would not* do that. That's not the question. The question is what are the constitutional boundaries on the government powers in this space.
