In addition to justice, gender equality has other things to recommend it (in Science Daily).
Older couples who live in Western countries and who enjoy more equality between men and women are most likely to report being satisfied with their sex lives, according to a new study on sexual well-being, aging and health that was conducted in 29 countries by a University of Chicago research team.
In contrast, older people reported less satisfaction with the physical and emotional quality of their sex lives in countries where men have a dominant status over women, such as nations in East Asia, and to a lesser extent, the Middle East, according to the results of the Global Study of Sexual Attitudes and Behaviors.
The study involved surveying about 27,500 people between the ages of 40 and 80, including equal numbers of men and women. The study is the first of its kind to document and compare sexual behavior and related satisfaction among middle-aged and older people worldwide. Across most of the countries surveyed, substantial majorities of people with partners remain sexually active throughout the second half of their lives.
