Actually, I'm hoping the "sexuality" aspect of the character doesn't get in the way of any serious character-building.
Sexuality, and even deep level relationships, still aren't handled as well as could be in most video game scripts. It's like how early comic books didn't take heroes' love stories beyond an innocent/superficial kindergarten-crush level, even when they were teens or adults who, by virtue of puberty, are more sexual beings.
Why can't sex and sexuality BE a part of serious character building? Hey, when it comes to relationships, people put stock into how many partners their boy/girlfriend has had. If they're a virgin or promiscuous (depending on how you perceive their numbers), it affects what you think of their character. Often deeply. The nature of sex, sexuality, and its effect on the human experience is deep.
