Hey filmmakers! I know this is a complicated, nuanced concept that takes years of study in advanced academic institutions, but I'm going to spoil the ending for you now:
It is not only possible, but likely, that two people of complimentary genders can be thrown together in a situation and not want to have sex with each other.I know, I've seen this happen. Like every single mixed-gender office ever. They don't all pair up, even if they're not already married. Even if they genuinely like each other as people. And sometimes, even if they are actually attracted to each other.
Now, some of y'all script writers appear to have advanced doctorates in Non-Trope Writing, because I've seen a couple movies lately where you didn't do this. And I appreciate you. But the rest of y'all need to get your shit together and get some schoolin' because the obligatory romantic subplot that serves to support the male character's story arc is boring, trite, lazy writing, overdone, and way out of proportion to reality. It's like watching a movie set in Harlem around the turn of the last century and seeing only 1 black face (of someone who happens to be in power during Jim Crow and yet not a main character). Like, do you even history bro?
The population is more than 50% "woman" - there needs to be more than 1 female character in a cast of dozens. When you add up all the various ethnicities together, white men are a minority - there needs to be more than 1 or 2 black dudes and possibly that 1 hot Latina in a cast of dozens. And I know that this one will be some seriously high level thesis work for you, but all those women and non-white people have their own stories going on that have nothing to do with supporting some white dude's personal growth, which even white dudes in the audience can relate to if you tell the story well (and if they don't just refuse to relate to on principle).
And when you look at all the times that people don't hook up with each other just because their genitals are complimentary, there needs to be more than 3 movies in the last 10 years that feature a mixed-gender cast that doesn't have the token woman character having sex with the lead male character or any sexual tension leading up to will-they/won't-they subplots.
Because it's totally possible to put an attractive woman and an attractive man* in a room together and have them not want to bone each other.
*I'm not even going to address the problem with body diversity or gendered double standards of age and/or "attractiveness" here - I'm mad enough already.
