If you discount species that only have one gender (which are homosexual by default), and species that change their appearance or body (like Changelings and Trills), are there any homosexual characters in the prime universe?
I am aware of Ezri and Lita being homosexual or bisexual in the Mirror Universe, but I am interested in the canon prime universe.
This question is explicitly about homosexuality. I am not focusing on those who are bisexual characters (there is one, Garak) or transgender characters (there is an entire episode covering that topic.) This is also not a question about the legal status of LGBT peoples in Star Trek - its about if there were any on screen characters who were homosexual (identified as such on screen or in the background by the actor or producers.)
