One in three young women regularly view porn, with many watching it on their smartphone, it has emerged.
Some 31 per cent of participants in the survey by magazine Marie Claire US said they looked at X-rated material once a week. And 10 per cent admitted that they had a daily porn habit.
The figures, which contradict the assumption that pornography is the preserve of males, also found that most of these women view images on their mobile phone.
Amanda de Cadenet, presenter of 1990s UK Channel 4 entertainment show The Word, helped design the survey and said that far from ruining women's lives, pornography is helping women find themselves.
Miss de Cadenet, who has reinvented herself as a fashion photographer and documentary maker, claimed the results contradict the idea that women feel threatened by pornography, as well as the perception that a generation's sex lives will be "ruined by childhoods bombarded by online sexual images".
