We have little reliable data on human sexuality because Select one: a. it is difficult for researchers to even broach the subject. b. until the AIDS crisis, there was little scientific demand for data on sexual behavior. c. government funding for studies of sexual behavior is easily accessible, but not many want to ask for it. d. there has been an increase in the use of inaccurate data over the last decade.

b. until the AIDS crisis, there was little scientific demand for data on sexual behavior.

Explanation:

Before the AIDS crisis, there was not so much interest on human sexuality from a medical and scientific point of view. While sexually transmitted diseases were already known, few had caused such a negative impact as AIDS, which became truly an epidemic.

Because of this short time frame, from the 1980s up to this day, scientists have not been able to accumulate so much information as to provide reliable data on the subject.
