Firstly, people are less lonely and degenerate than you think. This is /vt/ literally the most masculine place on the entire board, even with the trannies around.
Vtubers are made to appeal entirely to us, by acting more demure than what we're used to.
That is what is attractive.
It's like you say, its tits. Giant tits, little tits, exposed tits, bouncing tits, vibrating tits, tits covered in slime, those are all things we've had plenty of exposure to even outside of sexual content.
The value is so low that you can literally get millions upon millions of videos and images of tits for absolutely nothing.
It's not that easy to go find a reserved, quiet and classy young girl.
