There are some interesting models of desire that go beyond the usual common-sensical ones. I used to find these useful and fun to contemplate and still find them compelling.
Rene Girard’s Mimetic Desire: What is Mimetic Desire?
Jacque Lacan’s theory of desire is harder to explain and more convoluted. But he too sees desire as a mimetic social product than something biological. Unlike animals the human being is a unique product of language intersecting with the body. Because language can only go so far in its production of human subjects, it creates a lack - a yawning hole that can never be closed. It stays there like an existential void at the heart of human subjectivity. It’s sort of like a half rendered video game where the scenery turns to black pixels and wire mesh. From this lack desire springs - a fantasy that wholeness and closure are possible if only we get the longed for X, Y or Z which we fantasise the Other has. The Other is a hallucinated socially produced figure that we imagine to be un-lacking and complete e.g. Elon Musk, Dua Lipa or maybe just a moderately socially/sexually successful friend. Furthermore as infants our needs as babies are interpreted by powerful caregivers e.g. ‘johnny is hungry’, ‘johnny’s nappy is wet’. But our caregivers dispense not only bottles and clean nappies but also love and recognition. Over time biological needs get complicated and saturated by psychological demands for love/recognition and caregivers are internalised in the babies minds as powerful Others. But even the best caregivers, being only human are always getting it wrong and falling short. The demand for love is frustrated and what remains is desire - a sort of never-ending preoccupation with the Other and the fantasising of what the Other wants, has or doesn’t have. By this point the Other has been so thoroughly internalised that we don’t even realise we are doing it and simply experience it as desire. We are constitutionally desiring beings that desire as Others. Lacan would probably say that the goal would be to move away from demand - something that is rigid and concretely mimetic and into desire - one that is looser, socialised and tragi-comically aware of the ultimate futility of desire, yet realising there is no escaping it. Actual freedom would agree with Lacan and Girard insofar that desire is constitutional of ‘me’, but of course there it is possibly to bring desire to an end by ending ‘me’.
Hope that wasn’t too much of a head fuck 
Happy New Year everyone!!!
