"The truth is always a compound of two half- truths, and you never reach it, because there is always something more to say." - Tom Stoppard

"The SDS [Sexual Double Standard] has been a popular topic for researchers over the last two decades (e.g., Gentry 1998; Jacoby & Williams 1985; Marks & Fraley 2005; Sprecher 1989), but evidence for its existence has been elusive. For instance, Gentry (1998) employed a person-perception task and found that raters judged men and women who had an above average amount of sexual activity similarly. In another person-perception study, Marks and Fraley (2005) found that even in the absence of valenced sexual information regarding sexual behaviors (e.g., insinuating that having many partners is a negative characteristic), individuals tended to equally derogate men and women who had similar sexual histories."

Addendum: Translation - contrary to feminists' claims, there does not seem to be a sexual double standard - i.e. sluts vs studs (or studs vs sluts)
