I’ve read:

Dune

1984

The Long Tomorrow

[Radagast the Fool]

Dhalgren was interesting but there’s at least one section that graphically depicts homosexual sex...so you’ve been warned.
Delany’s earlier book Nova is one I’d have on my list, and no queer sex!!!!!!!!!!!!!
Dune and 1984 I read and liked, haven’t read any others on the list. I might add Stranger in a Strange Land, Lucifer’s Hammer, Alas Babylon..all 3 rather dated but classic IMHO.
