Sterling as a character is actually a pretty chill guy. Sure he wants to fuck like anyone does, but to actively raise and want to fuck his daughters without the help of mind/libido-transforming drugs? I don't know if I see it.
It’s not a fact that because of the hormones that Hunter himself poured in, Sterling became like this, initially, if you remember, Lucia said after her arrival that Hunter tried to have sex with her, after which Sterling told her not to eat anything that was near Hunter and not to drink . at the very beginning, these hormones got to Sterling, everything else thanks to Katherine, he became such a muscleman, when using such drugs and hormones you just can’t become strong, you also need to train hard, and this is the merit of Katherine and Amber))))
Sterling was just lucky that these drugs that Hunter wanted to use on all the girls came to him, of course everyone will say because of his height all the girls want Sterling, but this is unlikely, Katherine has always been the one who loves Sterling and she is the one who dragged him in training, everything has a price, even if it weren’t for these hormones, he could still rise up with his own desire and with the help of Katherine and Amber)))
