Japanese women share the trials of a life without climax

Chizuru looks every bit the party girl in her revealing, body-hugging dress. The image is confirmed when she admits frequently picking up guys at nightclubs. But when she gets them home, she says she suddenly undergoes a transformation.

"I become this shy woman who can't say what's on her mind," she tells Spa!, admitting that she's never had an orgasm despite considerable sexual experience -- an affliction apparently plaguing every second Japanese woman.

"I love sex," Chizuru says. "It feels really good when somebody plays with my clitoris. And I really love it when their finger goes deep into me. But every time I reach the stage where it's like, 'Oh, God, just a little bit more, keep going,' they all stop. And I never orgasm."
