Can sexual orientation change as we age?

Sometimes a person's life undergoes such a radical transformation that the change was inconceivable before it occurred. One such gobsmacking event happens when you unexpectedly fall in

love with someone who never would have pinged your "relationship radar" before. If a homosexual (or heterosexual) thought has never crossed your mind, for example, it can be doubly

astonishing when — _wham! —_ you suddenly find yourself attracted to someone of an entirely new gender. That may sound unlikely, but as researchers are discovering, a person's sexual

orientation is not carved in stone. In her influential book _Sexual Fluidity, _psychology professor Lisa M. Diamond chronicled her research on 80 nonheterosexual women over a period of 10

years. During that time, Diamond discovered, a significant number of the women had reported changing their sexual orientation. The most frequent cause for the U-turn? The

"switchers" had fallen in love with a member of the opposite sex. These women were not unhappy being lesbians, but love, it seems, really can conquer all — including a

person's lifelong sexual orientation up to the moment when she falls hard for someone of a previously ignored gender. The research on men shows somewhat less flexibility. But Diamond

and other researchers have compiled numerous case studies of gay men who spent years feeling (and acting) fully and comfortably homosexual, only then to fall unexpectedly in love with a

heterosexual woman. Recently, I interviewed two people who went through this sexual upheaval late in life themselves. Both said they had never even considered falling in love with someone of

the same — or opposite — gender until they reached their 50s or 60s. Only at that relatively late stage in life did they undergo startling 180-degree turns in their sexual orientation.

(While the facts of each case are accurate, I've used pseudonyms at the subjects' request.) Violet — a tall, striking woman of 60 with snow-white hair — had never married, but she

had enjoyed major love affairs with men. Intensely dedicated to her career, she became a TV executive at age 40. After her last relationship with a man ended in her 40s, Violet says she

"gave up on love." THEN SHE MET SUSAN. A marketing expert, Susan was in a pleasant but not passionate heterosexual marriage at the time. She valued her extended family — husband,

two children and their spouses, and four grandchildren — more than anything else. Susan had never been unfaithful. She had never been attracted to another woman. But from the moment she and

Violet began working together on a project, sparks flew, shocking both women. A physical relationship of 12 years ensued.
