Causes distress. Hypoactive means under active, so hypoactive sexual desire means under active sexual desire. But you decide how much is enough. What's enough for you may not be enough for someone else & vice versa. More importantly, there cannot be any disorder unless the under activity causes you distress. If you're satisfied w/your level of desire, then you're fine (although your partner might not agree).
No interest in sex. Normal sexual desire is relative. What is important is if a person is satisfied what their desire. Women more commonly have less desire than men. Large differences in desire can be a problem. See this link: http://www. Health. Com/health/gallery/0, 20778590, 00.html.
