Like it a lot!
I interpreted the story as kind of an allegory of life, modern life in particular - and even more particularly, modern romantic life.
You come across people, sleep with them, or have a fling - nothing that lasts. It's all transitory.
The memory from childhood, and the subsequent line saying that this was not the sort of meal the protagonist wanted now kind of spoke to me about how our needs/desires change as we grow older - we stop being kids, rebel against what our parents offered, advised and instructed us to do etc and take our own paths; for instance choosing to go against what they taught us and have sex with people we are (at least emotionally, if not literally) strangers to.
I took the nude man "feeding him" as being a literal reference to oral sex, but metaphorically I saw it linked to how many of us seem to wander from person to person, trying to fill a hole (not the physical kind...) or hunger inside of us... And his continuing onwards after this interaction for me demonstrates how sexual endeavors will not satisfy us, or our "hunger" without the emotional connection.
I took the protagonists desire for companionship to be that: wanting a relationship, someone to be with, in the hopes of ending the journey and the search we all go on.
For me the ending was positive - though I recognise it is ambiguous - and I would like to imagine that the protagonist found what they needed in the house they saw ahead... That it seemed to 'appear' before him put me in mind of a miracle, or a granted wish.
Sorry for the essay!!
REALLY liked your story by the way! Cool idea, well executed - you got a lot into a short(er) piece of writing - and I like the imagery(:
