As a woman ages, her ability to feel and express passion increases if she feels she can fully trust her partner to be there for her. If she feels she is being compared to another woman or that she has to compete, she cannot continue to open up. If she senses that he is having an affair or could have an affair, she shuts down. Like a delicate rose she needs the clear and clean water of monogamy to gradually unfold, one petal at a time. By clearly committing himself and assuring a woman that they are going to grow old together, her mate gives her the special support she needs to discover the fires of sexual passion deep within her soul.
