Aside from the many classic reasons for deception, a 1989 study in the USA has shown that potential sex partners will lie as to whether they have AIDS or are at risk. Over 30% of the men and 10% of the women surveyed indicated that they had told a lie in order to obtain sex. When asked hypothetically whether they would lie about testing postively for the AIDS virus, 20% of the men and 4% of the women said they would.
