If it wasn't rumoured before, you just started that rumour, so it is now.
More than one of my Lone Wanderers was.
Only one was a male character, and he took over Tenpenny tower with his fancy suit and devilish charms... then proceeded to lord over the place from on high with his snazzy hat and a monocle some generous modder was so kind to provide. Actually, he wasn't homosixual though... so that doesn't count. He was just magnificently well-dressed, and entirely sixually indiscriminate. Male, female, both, two legs, one leg, ghoul...
Ah, the life of opulence suited him well.
Had a few homosixual/bisixual female characters, as well... but usually only if they were 'Working Girls' up at Moriarty's/Evergreen Mills Bazaar/Rivet City
