Sex in America FAQ

Q: How many people were interviewed for the Indiana University National Survey on Sexual Health and Behavior?

A: The survey -- the largest ever of American sexuality -- included 5,000 people and asked hundreds of questions.

Q: When was the last exhaustive sex survey done in America?

Q: How many people were interviewed by Kinsey and his team?

A: Kinsey and his team conducted thousands of interviews with Americans about sex, over the course of 10 years.

Q: In the Kinsey survey, what percentage of women at the time of marriage had never achieved orgasm?

A: The Kinsey survey some 60 years ago found that 36 percent of women had not achieved an orgasm by the time of marriage.

Q: What is the "orgasm gap"?

A: The National Survey found that 85 percent of men said their partner had an orgasm when they had sex. But only about 64 percent of women said they had an orgasm when they had sex. The difference came to be known as the "orgasm gap."

Q: Are there ways for women to maximize their chance of having an orgasm?
