Lesbianity is a polytheistic religious movement which its sole purpose is to worship the relationship between two or more women. It shares many aspects with ancient Greek mythology, which is why followers of Lesbianity think the Greek island of Lesbos to be their sanctuary. Its main goddesses are believed to be Sappho, Artemis and Aphrodite.
The official church of Lesbianity began in 2003 in London, UK, while The Pope (official name of the highest function within the church of Lesbianity) was visiting the city. The official site of lesbianity is lesbianity.org
A girl's virginity from lesbionic sexual acts. This is regardless of her "straight" virginity--that is, whether or not she's had sex with a man.
Since it's hard to define a physical loss of virginity between two females, lesbiginity is mostly determined by personal opinions or feelings.
Ronery lesbian: I have no real interest in men, so I've never bothered to lose my virginity. I'm dying to lose my lesbiginity, though, if only I could find the right girl!
Bisexual girl: I lost my virginity to Ryan when I was ninteen, but I lost my lesbiginity to Megan when I was sixteen!
