share self-reporting exclusive heterosexual attraction remained largely stable between ages 21 (94.9%) and 32 (94.2%), with a small decrease at age 38 (92.9%). Sexual identity was only assessed at ages 32 and 38. At age 32, 0.9% of women and 1.3% of men self-identified as gay, and 2.9% of women and 1.7% of men as bisexual. Additionally, 1.5% of women and 2.2% of men identified as "other". At age 38, 1.1% of women and 1.7% of men self-identified as gay, and 2.6% of women and 3% of men as bisexual, with 1.1% of women and 0.2% of men identifying as "other". While sexual attraction changed more for women than for men, changes among men were more consistently to greater homosexuality, while changes among women past age 26 occurred equally in both directions (i.e., to both more and less heterosexual attraction). Researchers discussed several factors behind the changes, from age effects to cultural effects, with homosexuality, especially female homosexuality, becoming more socially acceptable in the West in the 1990s and 2000s. 2013–2014 According to results from the fifth wave of the New Zealand Attitudes and Values Study, which interviewed over 14,000 people about their sexual orientation, 94.3% of New Zealanders identify as heterosexual, 2.6% as gay or lesbian, 1.8% as bisexual, 0.6% as bicurious, 0.5% as pansexual, and 0.3% as asexual. No gender differences were found in the share of New Zealanders identifying as heterosexual (94.1% of men and 94.4% of women) or pansexual (0.5% of both men and women), but men were more likely to identify as gay (3.5%) than women (1.8%), and women were more likely than men to identify as bisexual (2.1% versus 1.5%), bicurious (0.7% v. 0.4%) and asexual (0.4% v. 0.1%). Women in all the non-heterosexual categories were significantly younger than women in the heterosexual category. Men in the gay, bisexual, and bicurious categories were also significantly younger than heterosexual men. Norway 1988 In a random survey of 6,300 Norwegians, 3.5% of the men and 3% of the women reported that they had a homosexual experience sometime in their life. 2003 In an anonymous survey of 1,971 male high school students performed in 2003, 1% self-reported having had a boyfriend and 2% having fallen in love with a man.
