Bro there is a difference, Grayson only does it out of necessity he is not sex maniac like Dane is. It literally mentioned he only sleeps around to release his pheremones or find his Fated partner or else he doesn't.
As for Dane also does Orgies btw, literally him and Joshua used to do orgies. And Dane does it for thrill and basically he is a sex maniac he has slept the double of Grayson also maybe that type of person they both are.
That's y Dane also regrets in the future for being a playboy in the past and regrets his past and lowkey wishes to be pure again for Grayson
The difference is Dane isn't going around acting high and mighty.
I know what goes on in the novel. So it's ridiculous to see you spinning the narrative. Dane was abused by his mother and has a skewed view of relationship. But you just narrow it down to "Dane bad too, Dane does orgies". Also did you forget the part where Grayson told someone that even if he found his fated partner, he will keep going to pheromone parties? Sure, he doesn't do it later, but think more before rushing to defend.

Who tf is Grayson calling vulgar?! Does he not see his own kind doing orgies and what not almost daily?!? (╬ ̄皿 ̄)凸 Also Dane my baby ┗( T﹏T )┛ It's NOT okay if you die ╥﹏╥ ╥﹏╥
