I agree with some of your opinions, but correct me if I'm wrong. about the fact that girls somehow feel like they are hiding needs within themselves or want to become whores, this doesn’t look right to me...
Firstly, remember how long it took Sterling to somehow win their love or sexual relationship, Okay Brenna, Eva, Katherine, they are too young when faced with their bad endings, it is noticeable that like Brenna also Katherine resists, even if under the influence of drugs , they try and try to fall behind and still the excitement takes over, so it’s unlikely that they could give their body to just anyone... All that happened there was due to a coincidence of circumstances that became thanks to Hunter’s substance, all these ventilations and all sorts of wine and other foods and drugs, if it weren’t for them, ALL of this wouldn’t have happened, Sterling showed up at the house at the wrong time at the time when Hunter had already prepared everything, if Sterling hadn’t shown up at the door, Hunter would have already fucked all the girls in 1-6 days under the influence...
and then, as you noticed, everything that Hunter once prepared affected Sterling and the girls are more aroused by Sterling, and now it’s also a mixture of love and sexual attraction to Sterling... Sterling is saved only by love, if not for these love, then a woman like Ophelia or Brenna should be wondering “What the hell, I feel sexually attracted to my son/brother” exactly what the hell?(That's why they are under the influence of Hunter, but LOVE for Sterling saves it) They would have planned it this way if it weren’t for feelings love and attraction to Mc...
