One of my mum's best friends discovered she was gay in her early thirties, after one marriage and a LOT of relationships/sexual encounters with men. According to her, she used to enjoy the sex with the guys.
25+ years later, and she's still a lesbian.
Who knows? Human sexuality is so hard to classify and explain anyway. Maybe women generally discover they're gay because they're influenced more by parental/societal/social pressure to conform to the heteronormative, reproductive 'ideal'.
