London, Feb. 27: How explicit should celebrities be in advising other women on how to explore their full sexuality?

Very, according to Emma Watson, who revealed she subscribes to a site which provides women with practical lessons on love-making - and how they can apparently achieve and heighten their orgasm.

While some have wondered why an attractive and healthy young woman should need to go to such a site when she should be able to discover the joy of sex through natural human relationships, the 25-year-old Harry Potter actress has received quite a lot of support, too, on social media.

According to one comment, "I guess this would be a good thing for women so that they could explore their own sexuality".

Emma, who is still remembered by film fans around the world as the 11-year-old girl who first played Hermione Granger in Harry Potter and the Philosopher's Stone in November 2001, has been trying for years to distance herself from her innocent little girl image.

And last week, during a conversation in London with 81-year-old Gloria Steinem, the American "feminist, journalist, and social and political activist" - she is perhaps the perfect role model for the actress - Emma certainly succeeded.

"Dr Watson", as she might now be nicknamed, has uncovered some rather elementary rules of lovemaking.

She disclosed that she is a paid (and proud) subscriber of OMGYES.com, a website which describes itself as "lifting the veil on women's sexual pleasure".

"Featuring scientific research and lots of video content - some of the videos are 'touchable', even, providing real-time feedback on your best efforts - OMGYES is all about putting the O in OMG (and that's an O for orgasm, FYI)," Cosmopolitan reported.

Emma herself declared: "I wish it had been around longer. Definitely check it out. It's an expensive subscription (£40) but it's worth it."

Cosmopolitan magazine said there was currently "a special offer" for £19.

The Sun newspaper puts its distinctive spin into its headline: "Hermoany Granger: Emma Watson plugs a sex website that helps women get a better orgasm."

The new online training programme, which studied the experiences of 2,000 American women aged between 18 and 95, "aims to demystify the female orgasm once and for all".

The research was done by Indiana University and the Kinsey Institute. Its tutorials offers advice to "anyone over 18 who wants to know how to make a woman reach sexual climax".

OMGYes states that "couples who explore new ways to increase pleasure are five times more likely to be happier in their relationships". Dreamed up by "engineers, educators, researchers and filmmakers' in New Jersey, OMGYes hopes to smash the century-old taboos around female arousal."

In 2014 Emma was appointed a UN women goodwill ambassador and helped launch the campaign HeForShe, which calls for men to advocate gender equality.

She is clearly a very bright woman. From 2011 to 2014, she split her time between working on film projects and continuing her education, studying at Brown University and Oxford University and graduating from Brown with a BA in English literature in May 2014.

She met and started dating fellow Oxford student Will Adamowicz in 2011, when she was a pupil at Worcester College, Oxford.

The couple split up in early 2014. Later in 2014, Watson began dating Oxford rugby player Matthew Janney. That relationship ended in November due to her "unrelenting work" schedules.

Reports say Emma "appears to have moved on following her 'horrendous' split from ex-boyfriend Matthew Janney. The Harry Potter star was spotted enjoying a lunch date with long-term friend Roberto Aguire recently, prompting speculation that the pair are now more than friends".

Aguire, 27, a produce and actor born to Mexican parents, grew up mostly in Switzerland and now lives in Los Angeles, leading him to describe himself as a "third culture kid".

"It's where your parents are a certain culture, you relate mostly to a different culture, and then you grew up in a place that's neither of those two cultures... and the cool thing about it, is you fit anywhere."

Emma and Sherlock actor Benedict Cumberbatch, 39, are among 11 prominent people who were recently appointed "visiting Fellows" at Lady Margaret Hall in Oxford.

The college's principal, Alan Rusbridger, the former editor-in-chief of the Guardian newspaper, said his appointees were "people drawn from a variety of backgrounds, callings and professions and we want them to form a bridge between our own academic community and the worlds they inhabit and represent".
