Yes, a bisexual might cheat on you if you date them. Guess who else might cheat on you? That’s right, a lesbian. A straight man. A straight woman. A gay man. A klingon. A hobbit. If you are willing to discount the romantic potential of an entire group of people based on their ability to have sex with somebody other than you, you better stock up on batteries. And what do you think the “B” in “LGBTQIA” stands for anyway? Bananas?
Bisexual women may be portrayed more often, but their sexual preferences have been frequently portrayed merely as an aphrodisiac for men or an extra hurdle for the men pursuing them. Female bisexuality also often goes unrealized beyond a single onscreen kiss between women; in other words, bisexual women are frequently seen only in fleeting encounters, rather than meaningful relationships, with other women.
