What about having sex with all the people you love, you really love, like your father, your mother, your brothers, your sisters, your friends, and so many more. Love does not require sex and sex is only good when it is associated to real love, not desire and that excludes many people not for love but for sex. Stop being a fetichist of Freud and his two, only two, god and his spirit flying over the dark water immensity, dimensions and maybe there is another dimension, a third one. Sex is Lacan’s lowest level of man, the physiological. Love is the highest level, the Phallus (not the penis), the super ego and death is the only rule that rules us all, lovers or not, sex addicts or not. Death is what remains when everything is gone. Libido and Thanatos is too simple. get into some Oriental, Buddhist phylosophy and you’ll understand we cannot reduce anything human to only two dimensions.
