Counselling and sex therapy charity Relate says it has seen a 40 per cent increase in men who simply cannot be bothered to make love to their wives and partners. The findings are a world away from just ten years ago, when hardly any men contacted them with a loss of libido. The main sufferers who call its helpline with the problem are generally aged between 30 and 50 and are married. Peter Bell, Relate’s head of practice, said: “Men used to come to us with impotence – now known as erectile insufficiency – but Viagra has sorted some of that problem. What we have is a lot of men who say, as women did in the 1950s: 'I can have sex but I do not want to. It’s not rewarding’.
