In general, between 4-10 is considered to be an average number of sexual partners for adult men and women. Ideas of what is too many, too few, or the "right" number of sexual partners vary from person to person.
People from the U.K. lead the way with the most partners, averaging seven sexual partners. Those from the Netherlands follow closely, with 6.9.
On the other hand, respondents from Italy averaged only 5.4 sexual partners, and people from Belgium had just slightly more (5.41). The average for the European Union was 6.2, which was also the average number of partners for people from Germany.
In the USA, the average number of sexual partners for men and women in the United States is 7.2. People in first-place Louisiana averaged nearly six times as many sexual partners as residents of bottom state Utah: 15.7 compared with 2.6. People from Mississippi, Kansas, and West Virginia all ranked on the low end with fewer than five sexual partners on average. On the high end, residents of Oklahoma, Nebraska, and South Carolina average more than 10 partners.
