Savant wasn't gay, just Creote (though he was attracted to Savant).
Marc Andreyko finally gave Obsidian a boyfriend over in Manhunter (Damon Matthews, who was Kate Spencer's co-counsel). He even planned on having them get married in Manhunter #50 had the series lasted that long. There's an internet rumor that Andreyko's pitched at least one Todd/Damon-centric story that was rejected.
Greg Rucka created Tommy Jagger over in Checkmate, who is the son of the original Judomaster. I don't remember there being any development of his personal life, though.
But yeah, other than Andreyko, Simone and Rucka I can't think of anyone else.
