Achieving youdaimonia

I kind of like the view that morality is other-regarding, so moral value excludes prudential value. On this view, it's morally praiseworthy for me to accept severe pain to cause you slight pleasure. But it's still better from the standpoint of overall value and prudential value for me not to go through this pain for you. If I accepted this view, my moral theory would be youtilitarianism. (In my own life, the theory of sexual morality it supports is shedonism.)
