New York, May 19: An app that teaches women how to masturbate has been removed by Apple from its iTunes stores worldwide.

Created by designer Tina Gong, ‘HappyPlayTime’ is a sex education app currently in development that teaches women how to masturbate.

The app uses light-hearted games to teach users about the female anatomy and provides lessons on different masturbation techniques.

“At the heart of our mission is the desire to see more women be vocal about their sexuality – in particular, about masturbation,” Gong said on the HappyPlayTime blog.

Gong described the app as a step towards sexual liberation for women and their bodies, the Huffington Post reported.

In a review, Apple told her the firm were “not interested in the concept”.

Now, Gong and her team are turning it into a web-based game.
