A true narcissist wants as many partners as possible, IF all of them idolize the Narcissist.
The above answer is correct they do want as many partners as possible. That way if one partner doesn't work out the way narcissist wants he/she has another lined up and ready to go. If you suspect you are with a narcissist-run!
Do yourself a favor and get as far away from them as possible. If you ask your narcissist if there is anyone else they will lie to you so you don't leave. Be sure of it as they are all pathological liars. That is one of the many horrible traits of Narcissism.
They think looks are more important than anything else.
Narcissists need to always be complimented; dramatize their lifestyle or indeavors;adored; admired, etc., and it's 'running out of supplies' for the narcissist when they want to come back to the partner they were with. This means the narcissist is not being supplied to boost his or her's ego and they know they can more than likely get the boost (like a drug addiction) from their former partner.
Narcissists invested more than non-narcissists, groups containing more narcissists destroyed the commons but had less to show for it, those working with them suffered the poorest harvest
No. Narcissists have a lot of faults, but other than being controlling and feeling superior than their peers they are no more apt to have a fetish then anyone else.
No more so than the rest of us.
Many people like their friends partner. That is perfectly normal. If you mean something more than 'like' then show your friend and his partner some respect and keep such matters to yourself.

They truly believe that THEY are normal. They think they are more humane than the rest of us!
