I know for a fact that lesbianism is very very common in GCC ... and yes it's all hidden and that's because of the EXTREME segregation between men and women, I'm not talking about the Islamic healthy segregation.. but about the EXTREME one.. where you live your whole life without even talking to anyone of the oppposite sex... Saudia arabia suffers from homosexuality the most! I had a friend who lived there and told me many frightning stories...
in GCC countries.. they have a common phrase: "boya" which means a female boy.... those girls act like boys and they have relationships with other girls! however, I've heard it's like a phase, and once they are married, they get over it! or maybe act like they got over it!
