I’m skeptical there could be this much difference in just one year. I suspect a sample error of some sort unless someone can suggest a good plausible reason for the increase:
Women are having wilder sex than a year ago with 76 percent admitting to using porn and four in five indulging in role play between the sheets, it emerged Wednesday in a new survey.
The English Netmums website survey found that despite three quarters of women having less sex — due to the demands of longer working hours — they are much more adventurous, The Sun reported.
The findings that 76 percent of women use porn is a 10 percent rise on the two-thirds of females who admitted to watching porn with their partners in a survey last year.
The most popular format is online porn, which is watched by 61 percent of couples.
My data set is very limited but I’m sure there has been an increase in the last 15 years.
I think I need to do some more research
