Qualitative data on Thai views of male and female sexuality and sexual
behavior are examined in light of hypotheses that have emerged from a
n evolutionary perspective. The data were derived through focus group
discussions and individual in-depth interviews. fn particular, we exam
ined how Thai married adults consider men's and women's sexual natures
to differ, what men and women seek in a long-term mate, and views of
spouse's extramarital sexual activities. In a number of key respects T
hai views conform to standard evolutionary predictions. The analysis a
lso illustrates how qualitative research techniques can generate usefu
l data for assessing these predictions.
