someone with the First Order (Phasma, Kylo, Hux, etc.) takes advantage of Poe's vulnerable position as captive and rapes him. He doesn't tell anyone, Finn springs him, and everything goes on as per the film.
Except a few weeks/months later when it comes to light after he tries to have sex with Finn (or Rey, or both, OP is not fussy) for the first time since it happened, and finds that he has panic attacks and freaks out at being touched.
With bonus points for his partner/s not noticing/mistaking his panicked breathing for excitement and continuing to push until he physically shoves them away and freaks out, making them feel really guilty once they figure out what's wrong.
Round 1 - Poe/Finn. Poe is traumatised by what the first order did to him. [non-con warning]
