Most girls are at least bi, but to conform, and blend in, they suppress their lesbian lust by rationalizing it away, by calling it something else. But with lesbianism surging and becoming more accepted--even envied---look for more and more women in the future to recognize their desire for what it is, and act upon it.
Maybe if you are going by how they identify and not going by have they ever had or fantasized about another woman. I don't travel in religious circles and have been around for over 60 years I can honestly say I haven't met a woman that was that uptight. Even the cattiest women in a moment will recognize the bond women can share without the stigma attached that men feel. Not sure about you but I have never invited a man to accompany me to the powder room, dressing room or offered to brush their hair.. Hope I didn't offend anyone here, just making my observation
