Some rambling thoughts.
it's kind of an evolution in the media.
The usual problem with gay characters, is that it always has that undercurrent of (loud whisper) sex!
At first, Gay people were mostly invisible. The comics code edited them out

1954 Code highlights
# Illicit sex relations are neither to be hinted at nor portrayed. Violent love scenes as well as sexual abnormalities are unacceptable.
# Sex perversion or any inference to same is strictly forbidden.
Then they become a joke or a monster, something to be feared, lurking in the dark, or something to be made fun of, and dismissed.
Slowly they could be more real characters, so long as they ended up either dead or deeply unhappy by the end of the story.
HIV and AIDS was a mixed blessing. It killed a lot of us, but it forced us to grow up and fight for more than not having our bars raided. We no longer were willing to allow the only depiction of us to be monsters, miserable or a bitter joke without comment or discussion.
Will and Grace was great for acclimating wide audiences to gay culture. Jack was over the top, but he was counter balanced by the near ordinary Will. The tone was different now. Jack was happy in his shallowness. He was not using humor to hide his inner misery. He apologized to nobody about being gay.
Gay characters became the plot device de jour, around the time of Will and Grace and Queer as Folk. It was strange watching them retrofit heroes and villains to be gay or trying to introduce new ones. Northstar might have been gay, or he could be an elf. WTF?
It seems to be sorting out, the worst of the refits and originals are being forgotten, the good ones are lasting. It's settling down so it's a aspect of the character, not the whole characters reason for existence. It's not being apologized for, or ridiculed or feared.
Gay character still do suffer from being sexless. "It's ok to be gay, so long as we don't have to see it." This discussion here touched on that. The gay characters are ok, so long as they are low key, ie don't show them kissing. (unless they are women? WTF?)
Anyway, I liked the two guys in Young Avengers or how it was handled in top 10 with Jet Man and his partner or ( wayback machine ) Enigma.
