So you do not see the distinction. You're repeatedly arguing past the point.

Nobody is saying trauma is something you can simply reason yourself out of after the event. Ive repeatedly pointed that out even. I'm saying the meaning we attach to an event beforehand affects how we interpret and experience it.

Yes, first experiences can produce strong associations. That doesn't establish that we should culturally frame someone's first sexual experience as a uniquely defining threshold where something is permanently "lost". If anything, that makes the framing more relevant, not less.

A traumatic first sexual experience may be traumatic because of what actually happened: coercion, pain, fear, humiliation, betrayal, whatever the circumstances were. But the additional belief that "this was my one special first time and now it's been irreversibly taken from me" is a separate layer of meaning, and that layer absolutely can be socially taught.

You're treating "trauma can form involuntarily" as though it disproves "cultural expectations can shape how experiences are understood" but those propositions don't conflict at all.
