ENThe article raises a question whether the concept of sexual revolution could be applied to the changes of sexuality in the Soviet Union. The case of one of the republics of the USSR, Soviet Lithuania is analysed. The dynamics of sexual policy, norms and behaviour that took place in 1944–1990 are examined to demonstrate what problems arise when applying the concept of the sexual revolution and a new solution is offered – the concept of sexual civil war. It is argued that this new concept points to implications that contradict the sexual revolution: the changes of sexuality are elongated and viscous, the conflicting traditional and modern norms and behaviour can overlap or entrench in separate social and cultural groups to create a kind of stalemate. Therefore the concept of sexual civil war does not stress on the changes themselves but a particular conflict in the process of a transformation of sexuality. Keywords: sexuality, sexual revolution, sexual mobilization, sexual civil war, Soviet Lithuania. [From the publication]
