This report is intended to provide reliable national estimates of some basic statistics on certain types of sexual behavior, sexual orientation, and sexual attraction for men and women 15-44 years of age, based on data collected in the United States in 2002.
. . .
The data are from the 2002 National Survey of Family Growth (NSFG), and are based on 12,571 in-person interviews with men and women 15-44 years of age.
Always interesting to get some hard data on the subject of sex. :)
