33 percent women in Britain watch porn once a week

London: As porn becomes more accessible in the digital age, women are no longer the bench sitters with one in every three women admitting to watching porn at least once a week, a new survey reveals.

The research by Spanish online survey firm Typeform for the international women's magazine Marie Claire showed 90 percent of the 3,000 female respondents watched it online and two-thirds said they watched it on their phones, The Independent reported.

The survey was part of a documentary project by photographer Amanda de Cadenet and the magazine.

The photographer felt womens' relationship to porn had been "hugely underreported".

"Porn is here to stay, and we have to learn to negotiate it, as sexual beings ourselves, who may or may not be viewers, and as partners," de Cadenet was quoted as saying.

In the survey, 31 percent of the women said they watched porn every week and another 30 percent said they did so a few times a month.

Asked what kind of porn they gravitated towards, 63 percent said heterosexual, 44 percent said lesbian while for 31 percent respondents it was a mixed bag. And 13 percent said they preferred gay male porn.

The majority of the women preferred to watch porn alone, with two-thirds saying they never watched it with a partner.

Over half of them agreed that porn had a positive impact on their sex lives.

"Most of our respondents, at least, are using porn to find what they want, and to figure out how to please themselves," de Cadenet added.

The majority of the respondents were aged between 18 and 34 years.
