Do women desire sex more for emotional intimacy or physical pleasure?

Younger women said intimacy, older women said pleasure.

Via Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships:

Psychologists Joey Sprague and David Quadagno surveyed women from twenty-two to fifty-seven years of age and found that among those under thirty-five, 61 percent of the women said their primary motivation for sex was emotional, rather than physical. But among those over thirty-five, only 38 percent claimed their emotional motivations were stronger than the physical hunger for contact. At face value, such results suggest womenâs motivations change with age. Or one could also argue that this effect could simply reflect women becoming less apologetic as they mature.
