Re: I think Bane and Scandal are great!
Besides Damon and Todd, there's also (/boyfriend's name):
Piper (/Micheal Forbes, /James-no-surname, /Earl "Fury" Povich), Tasmanian Devil (/Josh Barbazon), Hero Cruz (/Leander), Mikaal Tomas (/Tony?), Houston (/Rive-no-surname), Frostbite/Off-Ramp, Tommy Jagger, Creote, Josiah Power (/Rupe?), at least one version of Invisible Kid/Condo Arlik (Chemical King), and Extrano.
There's probably a few that I've forgotten, but working with what's there (and all of this is just my opinion/observations):
Several of these guys (Hero, Houston, Frostbite, Off-Ramp,and Josiah Power) are from the late 1990s/early 2000s. For whatever reason, most characters from that era just don't stick. They have a "shelf-life" of about three years, and then they're dumped into limbo.
Creote and Tommy aren't really "heroes". One's a mercenary, the other is an intelligence operative.
Extrano is in a class by himself.
I have no idea how Legion of Three Worlds ended, so I don't know if that continuity's Lyle and Condo were killed/wiped out of existence or not.
Piper will probably show up in the new Flash series at some point. Mikaal is supposed to be in the new Justice League book. Todd is currently in JSA (and is currently the only gay guy with a regular gig in the main DCU). Taz gets a cameo once or twice a year.
As far as relationships go, most of the guys seem to date civilians. The civilian boyfriends are rarely fleshed out, with the exception of Damon, who actually seems to have a life outside of being Todd's boyfriend. Condo and Lyle hooked up in one continuity, but in that one Condo never became Chemical King. Off-Ramp and Frostbite hooked up as Young Heroes in Love was ending; a "future" issue showed they spent several years together before going their separate ways.
I think DC's actually been a bit better overall to the gay/bi male characters than Marvel has, even if most of them are in limbo right now.
