Basically, Eros has a specific power that gives people lewd dreams when he's near them. Sexy Aura lol
So all this time, when Psyche was having horny night ventures with Eros, it was mostly a dream.
Eros explains this to Psyche but bcs Psyche wasn't taught anything sexual his entire life, he's very confused and horny and Eros is taking advantage of that confusion to "teach" him sex.

So that means Eros never assaulted Psyche and it was Psyche dreaming that "someone (Eros)" was touching him? Or he resisted at first and eventually succumbed later on?
Regardless, we still cooked 'cuz Eros is doing lvl 9000 manipulation tactics rn.
