Eh, the last bit is just my usual grumble about how popular media* likes to portray bisexuality as not actually existing, except when it's convenient for people to exploit the idea of sexual exploration for the titillation of the audience, while ultimately maintaining that the people engaging in bisexuality are just doing it to attract the opposite-sex person they
really want, who is portrayed as the true indicator of their actual sexual orientation.
Or their insistence that There Can Be Only One (Orientation), and that people† who start dating the same-sex or wind up marrying the opposite sex could never have been bisexual in the first place, but were secretly either hetero- or homosexual all along but confused about it until they settled down, with absolutely nothing in between.
But it looks like you're approaching the issue in a thoughtful manner from a non-exploitative perspective, so
.
* And then there's fandom, which just kind of fetishizes LGBT people in general, while also generally not actually respecting them as people in many cases, unfortunately.
† Not just fictional characters, but actual people. E.g. actress Anna Paquin, of X-Men and True Blood fame, who's had to go on record repeatedly in interviews that being happily married to a man does not in any way change the fact that she's bisexual and is still attracted to both men and women, and that no, it does not make her more likely to cheat on her husband than an exclusively heterosexual person would be.
