23.  The question matters:  Sexual intercourse = mixed-sex couples  Duration = women in same-sex relationships  Sex without orgasm = women in mixed-sex relationships  Longer durations could be an explanation for lower frequencies  Might indicate greater inclusion of a variety of sexual activities, including oral sex, foreplay, etc.  Frequency likely does not equate to quality  Bottom line = satisfaction & perception  Over 65% thought they were average in duration of encounters  No significant differences in overall sexual satisfaction Conclusions
