The index, which analyzes 45 countries, is not based on rumors but on a complex metric of six key indicators: the average number of sexual partners, the age at which virginity is lost, STI rates, the legality of prostitution, and social acceptance of premarital sex.

Czechia achieved a total GPI score of 305.50, with people reporting an average of 9.0 sexual partners over a lifetime, while the average age for first sexual experience is 17.2 years.

In addition, a high percentage of the Czechs considers sex between consenting adults outside of marriage to be morally acceptable, reflecting a notable shift in the country’s traditionally conservative social fabric.

Australia took the top spot with a score of 360.14 (averaging 13.3 partners), followed by Brazil in second place (340.66). Greece beat out other notably liberal nations such as Chile (4th), New Zealand (5th), and Germany (6th).

Italy ranks at the 7th place, suggesting a Mediterranean trend of high sociosexuality.

Sociologists suggest that Greece’s ranking may be attributed to its warm climate, a thriving tourism industry that encourages summer flings, and a modern culture that increasingly balances traditional Mediterranean family values with Western liberal attitudes toward dating.

The report also references the “Sociosexual Orientation Inventory” (SOI), a measure of how restricted or unrestricted a culture is regarding casual sex. Czechs’s high score indicates a significantly “unrestricted” mating strategy among its population.

While some may view the ranking with a wink, health officials note that high levels of promiscuity often correlate with higher STI transmission rates.

India, China, and Indonesia were named the least sexually liberal countries.
