Answer: D
The sexual revolution led to an increase in the number of people engaging in extra-marital sex. This was largely due to the fact that it directly challenged many of the social conventions and taboos associated with marriage, such as monogamy, fidelity, etc. By being open about having extra-marital liaisons, people expressed a desire to explore sex and find fulfillment outside of traditional marital relationships. This led to a greater acceptance of different sexual behavior and relationships. It also highlighted the importance of autonomy and individual choice in matters of intimate relationships. The normalisation of extra-marital intercourse played a major role in changing cultural attitudes towards marital relationships and sexual expression. This, in turn, strengthened the movement toward sexual liberation and individual freedom.
