>>3690338People have always been appealed to the combination cuteness and sexiness. The cuter a woman is, the sexier she is. It's common sense.
If you design a decent looking anthropomorphic character, you're sure to have a load of fans make lewds and porn of that anthro character. Extra points if she's an established character with a waifuable personality.
Pic-related is a very good example. Once that episode of Star vs. aired, some of /co/ went insane for her and some of her lewds were getting posted around, even though all she did was say "huh?" and "meh." for that one episode.
