A quick reminder, because I feel like it:
In the MCU and Sony X-men movies, we have had the following queer characters -
Mystique (trans, pan)
Cable (in a relationship with a male identified character, sexuality undefined)
Shatterstar (bi romantic asexual)
Rictor (gay)
Iceman (gay)
Colossus (gay in the ultimate universe)
Loki (trans, pan)
Eddie Brock (in a relationship with a male identified character, sexuality undefined)
Star-Lord (bisexual)
Psylocke (bisexual)
Black Widow (has been in a relationship with a female identified character, sexuality undefined)
Iron man (has had sex with men, sexuality undefined)
Valkyrie (bisexual)
Korg (gay)
Okoye (lesbian in comics)
Ayo (lesbian)
Wiccan (gay)
Bucky (bisexual)
But you probably only knew about these due to how they were portrayed:
Deadpool (pan)
Wolfsbane (wlw in the cinematic universe)
Mirage (wlw in the cinematic universe)
Negasonic Teenage Warhead (lesbian)
Yukio (bisexual)
