Freedom of Sexual Behavior

Well, now that marriage itself is becoming an outdated complex- with more and more adults being disillusioned with the sanctity of the commitment due to the fact that over 50% of marriages end in divorce- I do not feel that any decisions made by two consenting, tax paying adults should be considered criminal if it does no harm to them or any other individual. I think sex outside of marriage when you have agreed to the commitment of marriage should be a crime (at the very least a breach of contract) and may deter a lot of marital infidelity. I, as a Libertarian believe in limited government and a world in which all individuals are sovereign over their own lives and no one is forced to sacrifice their values for the benefit of others. Respect for individual rights is essential to freedom. Beyond individual actions and decisions, society or the representatives we elect to our state should set the standard for what is acceptable but not by their personal, moral beliefs but by common public consensus and only those issues which concern the group as a whole and not individual actions within. Each adult should have a right to engage in any activity that is peaceful and honest, the freedom to follow their own dreams in their own ways, without interference from government or any authoritarian power.
