In honor of Pride Month, here's a list of canonically queer characters in ASOIAF! There are far more characters than who I have listed, but I was only allowed 30 pictures per post, so I have tried to include central characters to the best of my ability. The progress pride flag has been used for characters with no confirmed sexuality.
Lady Jeyne Arryn, who served as head of house Arryn during the Dance of Dragons, and was seemingly pretty openly lesbian, and lived with and died naturally in her lover's arms.
Renly Baratheon - In both show and book canon, Renly is a gay man, and has a relationship with Loras Tyrell.
Daemon II Blackfyre - Canonically had a male lover, and had interest in Ser Duncan the Tall.
Jon Connington - A close friend of Prince Rhaegar Targaryen's. Many speculate he loved the prince, and he was confirmed by George R.R. Martin to be gay.
Elissa Farman - One of many, although the obvious favorite, lovers of Queen Rhaena Targaryen.
Oberyn Martell - In both books and show canon, Oberyn Martell is bisexual.
Loras Tyrell - In both books and show canon, Loras Tyrell is gay, and the lover of Renly Baratheon. It is speculated that Loras pursued Knighthood to remain unmarried without his sexuality being put to question, however his sexuality is widely known.
Queen Rhaena Targaryen - Queen Rhaena is a canonical lesbian, and had a harem of lovers, namely Elissa Farman, whom she was very openly close with.
Laenor Velaryon - In both books and show canon Laenor is a gay man and takes a few lovers.

Laena Velaryon - In book canon, Laena was rumored to have been a lover of Queen Rhaenyra Targaryen. Her sexuality is not confirmed.
