- Straight: Bob's in love with Charlie, even though he's never been interested in men before or since.
- Bob is extremely proud of his heterosexuality and will remind everyone of this fact every chance he gets, to the point of being extremely lecherous around women and disgustingly homophobic around gay men... except for Charlie, of course, with whom he's in a loving, committed relationship.
- Bob is gay, Alice is lesbian. They both fall in love with each other and get married.
- Downplayed: Bob just can't find any attractiveness in the members of his own gender... except for Charlie, whom he considers the epitome of masculine beauty, and the kind of person he wishes he looked more like.
- Alice is virtually everything the heterosexual Bob is looking for in a woman, but he simply cannot find her attractive.
- Bob is an Extreme Omnisexual willing to sleep with Anything That Moves (or doesn't move), regardless of species, ugliness, whether it's still alive or not, or whether it is related to him... except for Alice, as she absolutely disgusts him for whatever reason. Bonus points if the reason is something utterly trivial.
Bob: You're very pretty, Alice, but whenever I look at you I can't stop thinking about how you hang your toilet paper facing inwards. You Monster!.
- The normally gay Bob finds Alice uncannily and disturbingly attractive. Alice turns out to be a boy in disguise. Bob's gaydar rang true!
- The normally heterosexual Bob seems unusually close to Charlie and everyone is sure the two are secretly dating, until it's revealed that Charlie is his big brother.
- The normally gay Alice is in a committed sexual relationship with Bob, but she is only attracted to his personality and still finds his body kinda weird.
- Double Subverted:
- ...or so they think. Alice is actually transgender and ultimately transitions to living as a woman. Bob stands by her side throughout her transition, and stills finds her attractive. She was his exception after all.
- ...and lover.
- Alice finds herself fantasizing about Bob when a business trip prevents them from having sex for a week ... it seems Bob grew on her.
- Parodied: Bob is straight, and Charlie is the one exception. Oh, and Dennis. And Edward. Fred. And Gary. And Harry. Now that he thinks about it, he hasn't really dated any women. But he's definitely straight! We swear, honest!
- Zig Zagged: Bob is known by everyone to be straight, until he starts dating Charlie. But then it's revealed that Charlie is a woman... but Bob didn't know. And now that he does know, he doesn't like her anymore. Finally, Bob comes out as bisexual.
- Bob is bisexual and aware of it.
- Bob is heterosexual and doesn't like any man.
- Bob is homosexual and doesn't like any woman.
- Enforced: An Ascended Fanboy make Bob and Charlie a couple. Previously they were the favoured pairing of a particular fandom, while canon explicitly stated that Bob is straight.
- Lampshaded: "You know, Bob, bisexuality is a real thing."
- Invoked: Charlie is constantly teasing Bob with Gay Bravado interactions, all in the hopes that he might notice some day that he isn't just joking, but that he actually likes him.
- Exploited: Alice thinks Charlie and Bob would make a sweet couple, so she sets them up on multiple surprise dates together in the hope that brute forcing it will spark something between them.
- Defied: Bob only ever hangs out around women.
- Discussed: "Isn't it weird how often straight characters end up crushing on someone of the same sex?"
Alice: So wait, you're bisexual?
Bob: Nah, Charlie is just a special case for him.
- Deconstructed: After realizing his feelings for Charlie, Bob has trouble redefining his sexuality to account for this single exception, and ends up deliberately sabotaging their relationship so as to prove that it would never have worked out anyway.
- Bob recognizes the futility in categorizing something as complex as human sexuality, and decides instead to focus on the fact that he just really, really likes Charlie.
- Alternatively, Bob realizes how flexible human sexuality is and that being heterosexual, homosexual, and/or bisexual is about which sex/gender you find attractive in general or overall and not-so-much one individual. So he decides to label himself as heterosexual for the convenience, but to always remember his sexuality is not limited to it.
