I'm not at all sure if this would fit the bill, but I just finished and thoroughly loved
Light by M. John Harrison. I'll link my review there.
I almost DNFed this after the first 50 pages, but I'm glad I stuck with it, because Harrison's extremely talented at painting a picture of vibrant, living far-future places. I would not say the book has a whole lot of story to it, it's more the present moment of each character as they experience this and that. It felt to me much more true to life than a lot of books ever get close to.
That said, it's kind of horny. Sometimes, that's good because it treats sex in a pretty normal, realistic way. Sometimes, a scene just has it added to it in a way that doesn't always feel necessary. So, that's a downside.
Overall, though, I was really taken by it. Might be worth a shot.
