Prostitution and the sex discrepancy in reported number of sexual partners: “One of the most reliable and perplexing findings from surveys of sexual behavior is that men report substantially more sexual partners

undersampling and very high numbers of sexual partners are factored in, the discrepancy disappears. Prostitution’s role in the discrepancy

is not readily apparent because men are reluctant to acknowledge that their reported partners include prostitutes.” Proceedings of the National Academy of Sciences [Is this restating the obvious?]
