lights on or lights off
I'm going to assume you mean for sex.
This is kind of a peeve of mine.
Personally, I don't care if they're on or off.
What irks me is someone wanting/demanding they be turned off because they're insecure about their body.
If they want it dark so I don't really see them naked? Or, who knows, maybe they don't want to see me naked? Then we probably shouldn't be having sex.
Other than that, I've always preferred the question: "Drapes. Open or closed?"
There was a hotel across from where I once worked, a lot of people seems to prefer open. :)-
