Why Women Are Leaving Men for Other Women

Cynthia Nixon did it. Lindsay Lohan's doing it. TV shows are based on it. Is it our imaginations, or are wives and girlfriends ditching their men and falling in love with other women? New science says that sexuality is more fluid than we thought.

Lately, a new kind of sisterly love seems to be in the air. In the past few years, Sex and the City's Cynthia Nixon left a boyfriend after a decade and a half and started dating a woman (and talked openly about it). Actress Lindsay Lohan and DJ Samantha Ronson flaunted their relationship from New York to Dubai. Katy Perry's song "I Kissed a Girl" topped the charts. The L Word, Work Out, and Top Chef are featuring gay women on TV, and there's even talk of a lesbian reality show in the works. Certainly nothing is new about women having sex with women, but we've arrived at a moment in the popular culture when it all suddenly seems almost fashionable — or at least, acceptable.

Statistics on how many women have traded boyfriends and husbands for girlfriends are hard to come by. Although the U.S. Census Bureau keeps track of married, divorced, single, and even same-sex partners living together, it doesn't look for the stories behind those numbers. But experts like Binnie Klein, a Connecticut-based psychotherapist and lecturer in Yale's department of psychiatry, agree that alternative relationships are on the rise. "It's clear that a change in sexual orientation is imaginable to more people than ever before, and there's more opportunity — and acceptance — to cross over the line

Feminist philosopher Susan Bordo, Ph.D., a professor of English and gender and women's studies at the University of Kentucky and author of Unbearable Weight: Feminism, Western Culture, and the Body, also agrees that in the current environment, more women may be stepping out of the conventional gender box. "When a taboo is lifted or diminished, it's going to leave people freer to pursue things," she says. "So it makes sense that we would see women, for all sorts of reasons, walking through that door now that the culture has cracked it open. Of course, we shouldn't imagine that we're living in a world where all sexual choices are possible. Just look at the cast of The L Word and it's clear that only a certain kind of lesbian — slim and elegant or butch in just the right androgynous way — is acceptable to mainstream culture."
