Survey shows reason for cheating on husbands or partners * 25-34 year old women most likely to seek an affair outside marriage         * 1-3 months is the typical life cycle of an affair for 60.3% of AshleyMadison.com members         * 76.9% of unfaithful women still love their husband or long term partner        
A new survey of unfaithful British women from AshleyMadison.com, the world\'s leading site for extramarital affairs, shows that for 79.2% the over-riding reason for cheating on husbands or partners is an unfulfilled sex life.        
The survey of 10,245 UK women members of the website provides a snapshot of the changing face of infidelity in this country. Globally, female infidelity is on the rise and the UK is no exception.        
Noel Biderman, founder and CEO of AshleyMadison.com says: \"While women are gaining power in the work-place they\'re no longer prepared to accept a disappointing performance from their man in the bedroom. Many work long hours, they juggle family and professional responsibilities and find that a busy lifestyle can be both an excuse and a cover for cyber affairs and physical affairs.\"   The most common age group amongst unfaithful women is 25-34 year olds (35.1%), but the 35-44 year old age bracket is not far behind at 30.4%.        
\"Attitudes to infidelity amongst women are changing fast,\' adds Biderman. \"The taboo is disappearing, it\'s no longer a male preserve. With smartphones and access to the Internet 24/7, women have the tools to seek out and conduct discreet affairs that leave no \'digital lipstick\' in the way that Facebook does. It\'s as safe and easy as ordering a take-away!\"        
Unfaithful women seem to mirror cheating men who traditionally claim they still love their wives: 76.9% of Ashley Madison\'s cheating women say they still love their husband or long term partner and an overwhelming 95.1% say they are not in love with their affair partner. In line with this, only 11.6% say they would like to leave their husband or partner        
However, it seems that the one nightstand is still male territory, as an affair of one-three months is typical for 60.3% of the women surveyed and only 19.6% say they are looking for a one-night stand.         
Noel Biderman comments: \"Women tend to like a degree of stability; genetically they\'re not wired for one-night stands. But women are good at multi-tasking so there\'s no problem having an affair partner as well as a husband. 69% of the women we surveyed have only had one or two affairs.\"
