Betsy over at Camp McCarran whose into, 'Tall blondes' whom she can 'Jump their pants' (she was butt raped by a fiend).

Arcade Gannon is ousted as a homosexual if you have the 'Confirmed Bachelor' perk. As a male character I cannot hit on Cass successfully without her being all defensive but I have the option of sounding like a Legion butt pirate. From playing through the game for hours and reading the different outcomes with some of the companions I was surprised just how 'gay' this game is.
