Sorry, not right. This kind of effect would be more related to the need for social approval and to motivational effects of such a need. Intrinsic motivations do not depend on external reward. Sexual behavior is discussed in terms of very basic biological drives for reproduction, but in humans it has a very complex 'added structure' that is both biologically and culturally determined. For example, studies of 'mate selection' show that on average, men and women place different values on 'short term' sexual contacts and different weights on the attributes of a potential partner.
Physical attractiveness is rated as more important by women than by men.
Sorry, not right. This is the opposite of the observed measurements. Sexual behavior is discussed in terms of very basic biological drives for reproduction, but in humans it has a very complex 'added structure' that is both biologically and culturally determined. For example, studies of 'mate selection' show that on average, men and women place different values on 'short term' sexual contacts and different weights on the attributes of a potential partner. Financial success is rated as more important by women than by men in industrial cultures but not in agrarian cultures.
