Financial consumption was the only factor that predicted how many partners men wanted in the next five years and also predicted the number of partners they had in the previous five years, Kruger said. Being married made a difference in the frequency of one-time sexual partners in the last year, but not in the number of partners in the past or desired in the future.

The 25 percent of men with the most conservative financial strategies had an average of three partners in the past five years and desired an average of just one in the next five years. The 2 percent of men with the riskiest financial strategies had double those numbers.

"Men in the ancestral environment were valued if they were good providers. Now we have this new consumer culture, so basically we show our potential through the consumer goods that we purchase, rather than being a good hunter or providing protection," Kruger said.'
