Power dynamics I would never want in real life are surprisingly persistent in my imagination. I think the brain separates fantasy from values pretty cleanly once you accept that.
Fantasies about a significantly older man — much older than anyone I've actually dated. No idea why the age gap reads as shameful to me intellectually but there it is.
Public scenarios. Something I would genuinely never do, but the persistent nature of the fantasy is hard to explain. The exhibitionism element without any actual consequences I think.
A specific voyeurism scenario that I genuinely cannot trace to anything in my actual life or preferences. Brains are deeply weird and I've stopped trying to analyse it.
This is the most fascinating thread on the forum honestly. The disconnect between what we fantasize about and what we actually want is enormous. Fantasy is often about psychological states, not literal desires.
