As a disaster lesbian myself, I appreciate the comedic value of a woman who thought of herself as fully straight going through a groundhog day scenario often enough to become really good at seducing women as the most direct method of winning over her detractors she can think of, suddenly realising that maybe all those years has radically shifted her perspective and guys just don't do much for her anymore.
Could this story be appealing to the male gaze? Uh... maybe? Doesn't seem like the author has a particularly high opinion on men in general given how they're caricatured. Either way I know that this shit is hilarious.
Hell, if we really wanted to get into deeeep breakdowns and take a comedy story way too seriously, we could interrogate how such a bizarre and stressful situation could very well have long-lasting effects on someone. Not changing their sexuality mind, but in rebalancing how a latently bisexual individual could relate to both the same and opposite sex differently after all this.
