That's why I could easily concoct a sexual fantasy in my head of a stranger, a pornstar, a tv star, an anime character, someone emotionally distant to me in some way, because I can fill in the gaps to make that fantasy coherent and not repulsive to me.
But if I tried to do that with someone I know really well, like a very close friend or a family member, I simply couldn't do it because I know too much about them and thus constructing that fantasy brings up too much cognitive dissonance for it to ever possibly be immersive.
I think of my oshi in a similar way, which is why I can do it for any other Holo or Vtuber, but not my oshi.
If you can do that then so be it, to each his own, your powers of compartmentalization must certainly be stronger than mine, but I would still find it very weird.
