Note: For Cohen’s d values, * = small effect size, ** = moderate effect size, *** = large effect size (Cohen, 1988). Values indicate the Mean scores for SOI. SOI refers to a survey questionnaire called the Sociosexual Orientation Inventory. It is a measurement index to measure an individual’s sociosexuality, or the degree to which they are willing to engage in sexual activity outside of committed relationships. The survey consists of several questions related to mating behavior, romantic fantasies, relational emotions, and attitudes towards casual sex. By analyzing the responses, we can categorize individuals into different levels of sociosexuality, ranging from restricted (preferring monogamy and long-term relationships) to unrestricted (preferring casual sex and not investing as heavily in romantic relationships).

We also found that a lot of the same countries are repeatedly present on a list of who has the highest number of total sexual partners (body count). Find more stats on this in our report: “Average Number of sexual partners: by age, gender, and country

• 63% of female respondents and 64% of males were sexually experienced.
• Alcohol use, illicit drug use and young age at first coitus were associated with increased odds that females had had two or more partners in the previous three months, and being married lowered the odds; black or Hispanic race or ethnicity, alcohol use and young age at first coitus increased the odds for males, and being married reduced the odds.
• As the number of reported alcohol-related behaviors increased, the adjusted proportion of respondents who had recently had multiple partners rose from 8% to 48% among females and from 23% to 61% among men.
