Meet the Bermans

Until now, the main solution to sexual dysfunction has been faking it. But according to the Bermans, that has to stop. 'Don't start it, and if you are doing it, stop,' Jennifer advises. 'It's hard if it's been going on for years and you suddenly stop. Be prepared for your relationship to go into crisis because your partner will feel it like a betrayal, and will wonder what else you have been lying about. It becomes a very big issue and you have to make sure you have support.'

Both women are keen to point out that although orgasm is correlated with sexual satisfaction, many women are satisfied by the intimacy of sex without climax. 'We don't advocate that sex should be goal oriented,' Laura says. 'It only causes distress if it becomes an issue that deserves treatment.'

And this is the main message of For Women Only; that sexual dysfunction is treatable, both medically and therapeutically. Thanks to the Berman sisters, the medical fraternity might be getting that message, too.
