Attitudes toward unconventional and casual forms of sexuality and towa
rd extramarital relations as well as the appearance of parallel (extra
) sexual relationships are studied in three sexual generations. These
are constructed on the basis of sexual norms and practices prevailing
at the time of the sexual initiation of their members. The following s
exual generations are distinguished: the sexual generations of repress
ion born 1917-36, revolution born 1937-56, and ambivalence born 1957-7
3. The persistence of the sexual morals and behaviour patterns adopted
in youth clearly emerges from large national surveys conducted in Fin
land in 1971 and 1992. The generation of sexual repression appears as
the most restrictive in its attitudes toward unconventional and casual
forms of sexuality. It has least often engaged in parallel relationsh
ips. The generation of sexual revolution is consistently most permissi
ve in its sexual attitudes and behaviour. The youngest cohort, the sex
ually ambivalent generation, is permissive toward unconventional and c
asual forms of sexuality but family-oriented in attitudes toward marit
al fidelity. Nevertheless, it is free in its own sexual behaviour. Com
pared to young people twenty years ago, its members more often report
parallel sexual relations. The findings are interpreted by referring t
o current sociological discussions on individualization in (post)moder
n society.
