"A new study, published in the peer-reviewed Journal of Sex Research, analyzed surveys from around 12,000 students, and found that substantial changes in attractions, partners, and sexual identity are common from late adolescence to the early 20s, and from there into people’s late 20s."

"The results also show distinct differences between men and women, with female sexuality being more fluid over time."

"The early 20s are a time of increased independence and often include greater access to more liberal environments that can make the exploration, questioning, or acknowledging of same-sex attractions more acceptable and comfortable at that age."

"Straight people made up the largest group and showed the least change in sexual preferences over time."

"For example, 67% of women in the 'mostly straight discontinuous' group were attracted to both sexes in their early 20s. However, this number dropped to almost zero by their late 20s, by which time the women reported only being attracted to the opposite sex."
