When it comes to reporting the number of sex partners or how often they have sexual intercourse, men and women both lie. While men tend to overreport it, women have a tendency to underreport it. Although the story is not that simple and clear-cut, I have discovered some interesting reasons why this is the case – and why it matters to doing research on sexual health.
Lying is an inherent aspect of reporting sexual behaviors. For instance, more females report being a virgin (i.e., had not had sexual intercourse) despite having had genital contact with a partner, compared to males.
