Sex is fun and totally exuberance-enhancing. Most secularists who study human sexual activity believe copious exertions of this kind, particularly with a loving partner, foster physical and mental health benefits. (This is true for sex with others who might just be friendly, not quite loving.) A key variable affecting the quality of life enhancing aspects of sexuality is that relationships beyond the loving partner ideal are usually more complicated due to prevailing norms of a constrictive nature and are thus accompanied with risks and unintended consequences.
