Those who think women scoring more on the weighing scale do not score much when it comes to sexual behaviour, certainly need a reality check, for a new study has revealed that fat ladies have more sex than females with normal weight.

Oregon and Hawaiian researchers have found that a woman's weight does not seem to affect sexual behaviour.

Led by Dr. Bliss Kaneshiro, an assistant professor at the School of Medicine at the University of Hawaii, and Oregon State University professor Marie Harvey, the study was based on data from the 2002 National Survey of Family Growth that looked at sexual behaviour of more than 7,000 women.

In earlier studies it was Kaneshiro observed that obese and overweight women have a higher risk of unintended pregnancy than do normal weight women.

Thus, Kaneshiro studied the relationship between body mass index and sexual behavior, including sexual orientation, age at first intercourse, number of partners, and frequency of intercourse.

"Our analysis demonstrated that obese and overweight women do not differ significantly in some of the objective measures of sexual behavior compared to women of normal weight. This study indicates that all women deserve diligence in counseling on unintended pregnancy and STD prevention, regardless of body mass index," said Kaneshiro.

The study ruled out the widely held stereotypes that overweight and obese women are not as sexually active as other women, as the researchers concluded that it's the opposite that is true.
