Those that are shallow and lack capacity objectify and use, as such their capacity and density can be an extreme turn off and as such “lacking”.
Those with depth of desires and fantasies when combined with consent and honesty have a much deeper and richer view and hence can be viewed as a unicorn.
Does that make sense Federica M Micheli?
If you look at this from an intellectual point of view (remove the intimacy aspect) …. You have people that have the ability to be smart and those that have the capacity to utilize the smartness effectively (this is where in intimacy empathy and sympathy also play).
I can also see too if humor is applied also … how that can be either very funny or disgusting to a person depending on their POV (no judgements or shame from me either).
