From the viewpoint of self psychology people are limited in their ability to seduce because they have a self. You can't maintain perfect mirroring because you get tired, their turn-on is your squick, etc. In the early stage of peak ensorcelement (limerence) people don't see the "small signals", they miss the microexpressions, sarcastic leaks, etc. -- they see what they want to see. But eventually that wears out.

It can be puzzling that people fall for "romance scams" with people whose voice they haven't even heard but actually it's actually a safer space for that kind of seducer to operate because the low-fi channel avoids all sort of information leaks.
