Editing Heteroflexibility (section)

== Prevalence ==
National surveys in [[Canada]] and the [[United States]] as of 2012 show that three to four percent of male teenagers, when given the choice to select a term that best describes their [[Sexual orientation|sexual feelings, desires, and behaviors]], opt for "mostly" or "predominantly" heterosexual. With "100% heterosexual" being the largest assumed identity, "mostly-heterosexual" was the first runner up in self-identification.<ref>{{Cite journal |last1=Savin-Williams |first1=Ritch C. |last2=Joyner |first2=Kara |last3=Rieger |first3=Gerulf |date=Feb 2012 |title=Prevalence and Stability of Self-Reported Sexual Orientation Identity During Young Adulthood |journal=Archives of Sexual Behavior |language=en |volume=41 |issue=1 |pages=103–110 |doi=10.1007/s10508-012-9913-y |issn=0004-0002 |pmid=22302504 |s2cid=43225099}}</ref> Of the 160 men interviewed for a study in 2008 and 2009, nearly one in eight reported same-sex attractions, fantasies, and crushes. The majority had these feelings since high school; a few others developed them more recently. And in a national sample of young men whose average age was 22, the "mostly straight" proportion increased when they completed the same survey six years later. An even higher percentage of post-high-school young-adult men in the U.S. and in a handful of other countries (including New Zealand and Norway) make the same choice.<ref>{{Cite web |date=3 November 2010 |title=Mostly Straight, Most of the Time |url=http://goodmenproject.com/featured-content/mostly-straight/ |access-date=30 January 2011 |publisher=goodmenproject}}</ref>{{Better source needed|date=September 2021}}

An analytical review article looking at the experiences and meanings of same-sex sexual encounters among men and women who identify as heterosexual found that a large portion of same-sex encounters occur among those who identify as heterosexual. The prevalence of same-sex sexuality among heterosexually identifying men and women is not universal. 13.6% of women and 4.6% of men reported attraction to members of the same sex, while 12.6% of women and 2.8% of men have at some point had a same-sex sexual encounter.  Findings from the National Survey of Family Growth data from 2011 to 2015 revealed another insight into how much same-sex attraction and behavior can be accounted for by heterosexually identifying people. They found that 61.9% of women and 59% of men with currently reported same-sex attractions identified as heterosexual. Similarly, 65.2% of women and 43.4% of men who have engaged in same-sex sexual encounters identify as heterosexual.<ref name=":0">{{Cite journal |last1=Hoy |first1=Aaron |last2=London |first2=Andrew S. |date=July 2018 |title=The experience and meaning of same-sex sexuality among heterosexually identified men and women: An analytic review |journal=Sociology Compass |language=en |volume=12 |issue=7 |pages=e12596 |doi=10.1111/soc4.12596|s2cid=150362480 }}</ref>
