Nothing stupid about this at all!
Individual sexuality is wild, and is far more dependent
on personal experiences – the good and the bad –
the imagined and dreamed about scenarios
and role models in real life and in fiction,
on specific contexts and strange yearnings,
than it does on some hard Frankensteinian M/F switches.

We all have our deviations and drives to experiment
beaten out of us by the social norms and their enforcers,
so we default to one of the approved identities,
regardless of how we really feel.
It's never "I like men in super-specific situations",
but "Thank You For Subscribing To Heteronormativity,
Hope You've Read The EULA You've Just Signed,
And Have Fun Being A Cottagecore Tradwife,
An SUV Karen Mom or A Truck Stop Barfly!"

There's also the curiosity and fascination
about the category you've not been overexposed to,
like when you'd grown up as a woman surrounded by women,
and the the men were that bizarre Other Tribe.
There is both a threat and a promise in the unknown.

Both the endless hordes of female Omegaverse and Twilight fanfic writers,
and the legions of anime girl-obsessed basement-dwelling guys
have proven that one can be fascinated and obsessed
with the opposite gender in a way that is
violently antithetical to pursuing
a relationship with them.
