Personally I don't want sexuality in my video games any more than I want going to the toilet in them. I mean Persona has dating and yes you can take a leak to make yourself feel better but Im talking about sex scenes and overtly sexual content.
Can't stand 'em in movies and don't want them in my games. They add nothing to the story so I see them as being filler.
It we are talking about a character's orientation then I don't care are long as they aren't some irritating stereotype.
