lust is to all, intimacy is to one. morality is intimacy and not lust. Intimacy is moral because you consider the other person as yours and you don’t harm yourself, Do you? so its not selfish so its moral, it’s based on the emotion of love. Thats why marriages are considered so moral and so being in a relationship with one is moral. But without love again it’s no intimacy even in marriages or relationship. On the other side love/affection can happen with everyone, so you should have the freedom to love all when you are in an intimate relationship with one person and affection towards others should not be confused with intimacy, that’s where trust comes. So possession and love is very much necessary in intimacy.
