Narcissists can either be very cold towards sex and some like to be in total control and demand a lot from their sexual partner. A sex-loved addict just loves sex, but in many cases will give as good as they get (affection and warmth.) Most Narcissists loathe women in general and see them as objects rather than someone they should love and trust. A person that is a sex addict can love.
Sex addiction is an addiction. the partner of a sex addict has no influence on their sexual addicted encounters. Sex is a drug to them. Sex heals wounds that have nothing to do with the current partner.
