I did my PHILO3 thesis paper on this..
It would seem you guys have it right..
Just to add a little more, everyting a person wants/desires is directly or indirecly linked to a sexual desire originating from that persons past...
You like kiwi = its sexual thing.. The senses that are stimulated remind of enjoyment you had in the past eating that kiwi.. And that enjoyment may have come from other roots..
Ok this can complicated, so I better stop...
