What the bible says about dating relationships
The Standard Cross-Cultural Sample describes the amount of extramarital sex by men and women in over 50 pre-industrial cultures.
The amount of extramarital sex by men is described as "universal" in 6 cultures, "moderate" in 29 cultures, "occasional" in 6 cultures, and "uncommon" in 10 cultures.
However, this does not take into account the relative population of each of the societies studied, and the actual practice of polygamy in a tolerant society may actually be low, with the majority of aspirant polygamists practicing monogamous marriage.
Convenience samples do not accurately reflect the population of the United States as a whole, which can cause serious biases in survey results.
Biologists, biological anthropologists, and behavioral ecologists often use the term monogamy in the sense of sexual, if not genetic, monogamy.
Human monogamy's legal aspects are taught at faculties of law.
The only way to get scientifically reliable estimates of extramarital sex is to use nationally representative samples.
Three studies have used nationally representative samples.
The amount of extramarital sex by women is described as "universal" in 6 cultures, "moderate" in 23 cultures, "occasional" in 9 cultures, and "uncommon" in 15 cultures.
