You know, if we're talking about the Classical world, "rape" means to carry somebody away.
The DM gets to decide how the monster behaves (one of the perks, eh?). Sure the Satyr would like to have sex with... well, everything. But does it physically violate the character? That's up to the DM. Maybe it tosses her over its shoulder and tries to carry her to a secluded glen; when it gets there, it hopes to woo her and win her over with its charms (maybe it's a vain beast as well). Satyrs are typically presented comically in the ancient world. Maybe it thinks it can seduce her merely by displaying its exaggerated 'attribute'.
I can see a scene where the female PC wakes up in a lush, secluded glen with her host setting out copious amounts of wine and fruits. He plays a flourish on his pipes, and then 'presents' himself in full exposure, with a look on his comically ugly face of "So whaddya think, baby?" Then our heroine has to extract herself from the situation without violating the creature's undoubtedly inflated sense of the rules of hospitality. Farcical, but still a little dark... and more tale-worthy, don't you think?
