In a rush to make the play on words, which I admit was clever, you have missed the argument.
The issue was not whether banning this practice or that perversion was something we wanted. GraceC's original point was about the practicality of enforcement. And yes, as it turns out, we have many laws on the books that deal with crimes inside ones home, and we are enforcing them just fine.
Now back to your question about oral sex. I will answer it this way. A few years ago, a German pervert killed and ate another German pervert... with his consent, in the privacy of his bedroom. Do I want the police "in our bedrooms" to ensure that does not happen again? You bet!
We have to allow society to draw moral lines that can only be crossed illegally. My belief is that, over time, a free society will draw the lines appropriately.
I remember that. One answered the other's newspaper ad IIRC. Those were two sick b@#$%^ds.
