"They looked at 35 countries based on data from Statista."
Statista is a website that neither does any surveys nor any research, they just post data from other sources including the government, academe, and non-profits. The way they make money is that you have to pay to go to the original source to find out who conducted the survey, how many people were surveyed, and how the information was collected. Anytime you are basing an essay on a study, you really should mention or have a link to the methodology. Don't be a cheapskate.
I've been to Islamic Turkey and find the idea that Turkish men have had that many female lovers laughable. Cohabitation before marriage and premarital sex is very rare in Turkey, as is divorce. The sultan had a harem, but let's get real.
