The experience of teen girls who have same-sex relationships is markedly different from that of gay males, recounts the Washington Post in "Partway Gay?":
Outside of conservative religious circles, the common understanding for years has been that homosexuality is largely genetic, based on physical attraction, and unchanging. Though an easy model to understand, if not accept, it has a major flaw: It is derived almost exclusively from male subjects.
Recent studies of relationships among women suggest that female homosexuality may be grounded more in social interaction, may present itself as an emotional attraction in addition to or in place of a physical one, and may change over time.
The greater fluidity of sexual orientation among many (not all)
women as compared with men can't be dismissed, though it makes for
a more complicated picture of gay life in the 21st
century.
