Women are more susceptible to report bisexuality than men. A study claimed this, adding that men have a higher likelihood of reporting being either 100% heterosexual or 100% homosexual.

Author Elizabeth Aura McClintock of the University of Notre Dame studied the data of 5,018 women and 4,191 men as they became young adult from adolescence.

The participants were 16-years-old in Wave I, 22 in Wave III, and 28 in Wave IV. She found three times higher chances in women to change their sexual identities from Wave III to Wave IV of Add Health than men.

The study identified Add Health participants, who were not asked about their sexual identities until Wave III, as 100% heterosexual, mostly heterosexual, bisexual, mostly homosexual, and 100% homosexual.

According to McClintock, odds were high for women to get attracted to both men and women. This gave women greater flexibility in making a partner choice.

Women with more education and those who were more physically attractive were increasingly identified as 100% heterosexual than other women in Waves III and IV of Add Health.

With favorable options in the heterosexual partner market, chances increase for women with some degree of attraction to both males and females to get attracted towards heterosexuality.

"Women who are initially successful in partnering with men, as is more traditionally expected, may never explore their attraction to other women. However, women with the same sexual attractions, but less favourable heterosexual options might have greater opportunity to experiment with same-sex partners", says McClintock.
