According to Osho, sexual ethics means honoring sex as a natural, value-neutral life energy to be lived in love, not by law. Repression breeds perversion; love is the only legitimacy for relating. When love ends, bonds should end. Most importantly, join sex with meditation—use orgasmic no-mind to sublimate energy into creativity, awareness, and ultimately enlightenment.
Sex is natural; be loving and honest, and let intimacy become a doorway to calm awareness instead of a duty or guilt.
