Tjejer är inte intresserade av sex! [/mod]

As part of the International Sexuality Description Project (ISDP), the SOI was translated from English into 25 additional languages and administered to a total sample of 14,059 people across 48 nations. Responses to the SOI were used to address four main issues. First, the psychometric properties of the SOI were examined in cross-cultural perspective. The SOI possessed adequate reliability and validity both within and across a diverse range of modern cultures. Second, theories concerning the systematic distribution of sociosexuality across cultures were evaluated. Both operational sex ratios and reproductively demanding environments related in evolutionary-predicted ways to national levels of sociosexuality. Third, sex differences in sociosexuality were generally large and demonstrated cross-cultural universality across the 48 nations of the ISDP,

Using
data from 53 nations and from over 200,000 participants
surveyed in a recent BBC Internet survey, I examined
cross-cultural patterns in these five parameters for two
sexual traits—sex drive and sociosexuality—and for
height, a physical trait with a biologically based sex difference.
Sex drive, sociosexuality, and height all showed
consistent sex differences across nations (mean ds = .62,
.74, and 1.63). Women were consistently more variable than
men in sex drive (mean female to male variance ratio =
1.64).

In a comprehensive review, Baumeister, Catanese, and Vohs
(2001) surveyed a broad range of research results indicating
that, on average, men’s sex drive is higher than women’s. In
summarizing their findings, they observed that ‘‘[t]here were
no measures that showed women having stronger drives than
men’’ (p. 264). As part of their review, Baumeister et al.
examined research results fromseveral non-western societies,
and they concluded that these studies were consistent with
other studies showing that men have higher sex drive than
women. However, they acknowledged that ‘‘[r]igorous data
from other cultures are difficult to find…’’ (p. 268).
There is little quantitative information on the magnitude
of sex differences in sex drive. In a recent study (Lippa,
2006, Study 3), I computed a reliable (a = .82) multi-item
self-report measure of sex drive, and in a sample of over
1,700 participants, heterosexual men and women showed a
large difference in their self-reported sex drive (d = .82).
Furthermore, women were more variable than men in their
sex drive (female to male variance ratios were 1.43 for
heterosexual participants). Using a less reliable one-item
measure of sex drive to assess more than 1,700 college

students (Lippa, 2006, Study 1), I found a smaller but still
substantial difference in heterosexual men’s and women’s
sex drives (d = .58) and, once again, women’s self-reported
sex drive was significantly more variable than men’s
(female to male variance ratio = 1.30). Ostavich and Sabini
(2004) used a four-item scale to assess sex drive in 129
college men and 148 college women, and their statistics
translated to a very large sex difference (d = 1.17). Their
data also showed women to be more variable than men in
sex drive (female to male variance ratio = 1.60).
An ambitious study by Schmitt (2005) has provided the
current gold standard for estimates of sex differences in
sociosexuality. Using SOI data collected in 48 nations,
Schmitt found d values for sex differences that ranged from
.30 to 1.24 in various nations, with an overall mean value
of .74. Schmitt concluded that ‘‘[t]hese results…place sex
differences in sociosexuality…among the largest and culturally
most robust ever documented in the domain of sex
and human mating’’ (p. 262). Schmitt further noted that
‘‘[w]ithin the constraints of the current methodology and
sampling limitations, it can be concluded from these results
that sex differences in sociosexuality are a cultural universal,
supporting the basic tenets of parental investment
theory…’’ (p. 265).

A second important finding that distinguished
sex drive from height (and from sociosexuality as
well) was that, across nations, women were consistently
more variable than men in sex drive. Sex drive was the
only trait to show such a powerful sex difference in trait
variability.

Furthermore, women were more variable than men in their
sex drive

once again, women’s self-reported
sex drive was significantly more variable than men’s

Their
data also showed women to be more variable than men in
sex drive

across nations, women were consistently
more variable than men in sex drive. Sex drive was the
only trait to show such a powerful sex difference in trait
variability.
