Anyways I know I could be opening a big can of worms by making this topic, but I thought it would be interesting to discuss the homosixual and bisixual characters in the game. I've taken the liberty to make a list of every known character who is either gay or bisixual.
Clover: The slave bodyguard that can be purchased by Eulogy Jones. She appears to be bisixual as she will flirt with the main character regardless of his or her gender.
Nova: The prosttute working at Moriarty's Saloon who also seems to be bisixual. She will sleep with the main character for caps regardless if they are male or female.
Anthony Ling: The owner of the clothing store in Tenpenny Tower. He seems to be based off the architypical "gay fashion designer", he is obsessed with pre-war fashion and often uses the word "fabulous". Also Millicent tells her husband about how he's always teasing the male guards and when talking to Chief Gestavo he tends to flirt with the security chief who always rejects his advances.
Carol and Gretta: The two ghouls who run Carol's Place in the city of Underworld. It seems that they are quite possibly a lisbian couple as Carol mentions that she and Gretta have "been together" for many years and admits that Gretta was always jealous of her adobtive son Gob. Gretta also seems to be very protective of Carol.
I think Anthony is the one who is the most obviously gay, but at the same time I find it a little offensive that his character is such a negative stereotype. However I guess that was done on purpose as every resident in Tenpenny Tower is a negative stereotype based on the concept of snooty rich bigots.
