how to talk about sex like we talk about being hungry

most days I have a conversation with my wife that goes—Are you hungry? —Yes, I'm famished —no, I just ate —I'm feelin' snacky etc. etc. I feel like it could be very useful to apply the lessons in this neat talk about using ordering pizza as a metaphor for sex and consent and have similar check-ins about our libidos. but I'm having trouble coming up with the same depth of vocabulary. Horniness and arousal don't seem to have the same range of nuance that runs from stuffed to peckish to starving. Or maybe there are words and I just don't know, that's what I need your help with.

1 what to ask? I don't like 'are you horny?' it's so Austin Powers. I wish there was something more nuanced—a more general check in that can set the mood for the night

2 how to respond? What are some good words or expressions that convey a full range of arousal and down-ness from 'not interested' to 'I'm game if you are' to 'please, please, please, yes!'

3 any other ideas or communication techniques that you find helful for this kid of conversation. Thanks :)
