To Narcissist there are two kinds of Sources of Narcissist Supply. They will feed off a Low Grade/Quality Source, when they can’t manage to trap a High Grade/Quality Source of Narcissistic Supply.
The Narcissist is the Standard used to judge the quality of their Source of Narcissistic Supply.
If the Supply Source is better Educated (this is major consideration with “Cerebral Narcissists“) then it is deemed to be a High Grade/Quality Source. If you make more money or have a higher job title, then again you are deemed to be a Good High Grade/Quality Source of Supply. If you are physically better looking, then again you are a High Grade/Quality Source of Supply.
Being classified as a High Grade/Quality Source of Narcissistic Supply guarantees really awesome sex. The Narcissist wants to impress such a sex partner. They will get a rush if they can sexually impress a High Grade/Quality Source of Narcissistic Supply. Narcissists always look up to people whom they consider to be a good High Grade/Quality Source of Supply.
On the opposite end of the stick is what Narcissists classify as a Bad or Poor, Low Grade/Quality Source of Narcissist Supply. This type or person will not be someone whom the Narcissist will ever look up to. Such a person will likely be far less educated (again a major big deal with Cerebral Narcissists) than the Narcissist. The person will earn far less money. They will have a much lower job title. This is the type of person that the Narcissist disdains. But since a High Grade/Quality Source of Supply is unavailable, they will feed off the Low Grade/Quality Source.
Since they do not look up to and actually have a disdain for such a Low Grade/Quality Source, the Sex will be far from satisfactory. To a Narcissist, Sex with a Low Grade/Quality Source of Supply is not much different than Masturbation.
To top things off the Narcissist will then complain to the Low Grade/Quality Source of Supply, that it was the Source’s fault for the lousy sex. It takes two to Tango, but the Narcissist could care less to Tango in this case. The Low Grade/Quality Source of Supply ends up with a lowered sense of self after such sex. Perfect for the Narcissist, because it makes the Low Grade Source of Supply easier to further manipulate.
