Before and after World War II, how did German sexuality change? How did family values and divorce rates change, and were the Germans still of pure blood?

Between 1883 and 1957, when the social security system was established, more than 60% of the respondents to the German Social Survey chose to settle down in their families and have children to decide on their old age, but after the improvement of the insurance system, to a large extent, individuals no longer rely on their children as the goal of their survival.

Sexuality has been the subject of various feminist movements since the early 1900s, and divorce and family issues have entered a new phase of development since then. Sexuality has long ceased to be a man-dominated behavior. It has also been gradually separated from marriage, and although the trend has alternated between openness and conservatism since then, sexual behavior has always been determined by women. So on the whole, premarital sex is becoming more conservative. But more than half of the German men surveyed after marriage had sex with someone other than their wives. This result makes a lot of people instantly collapse.
