idk yall my take is that ilya is both more vers and more of a switch than shane, and crucially he truly enjoys all the various roles and positions
“he’s a dom” “he’s a service top” HE’S BOTH. HE BOTHS IT
he genuinely enjoys domming shane. did we not all see that “wow” as he nearly came on the spot the first time he told shane to get on his knees? he fucking loves ordering shane around and taking shane apart. he thinks shane is 100% seriously perfect, and even more importantly, shane is usually in control of himself and his environment. he orders everything in his life very precisely. for shane to give up that control to ilya is one of the hottest things ilya can conceive of
as connor himself said, ilya is someone who’s lacked a lot of control in his life which really feeds into him enjoying being in charge during sex. conversely, ilya is also someone who’s received too little care in his life, who’s been constantly criticized by abusive family, so being told he doesn’t have to perform, he can let go, he’s doing so good, etc would also be just as fulfilling for him
the widely agreed upon first raw fuck in e6 is the perfect example of this, ilya’s red-faced and looks completely gone while shane’s shoving his thumb into his mouth and ordering him to fuck him. how long has shane been torturing him???? we’ll never know
i think shane is almost certainly the first sex partner ilya’s felt safe enough with to actually relinquish control like that, hence why he’s so fucking lost to it. he’s never let himself be vulnerable enough for that before
(i can see an argument that he might sometimes let sveta dom him, but if they did i think he kept it very surface level, very playful, and would’ve run for the hills if she’d tried to take him to an actually vulnerable place (which she’s definitely smart enough to know, so i can see her occasionally ordering him to eat her out or whatever she felt like in the moment, but nothing like what we see him do with shane at the cottage))
tl;dr ilya loves sex & gets so many of his needs met through sex that i just can’t see him being anything other than a switch
