The lexicon of sexual orientations has already given us ‘demisexuality’, ‘pansexuality’ and ‘bicurious.’

But according to experts, we will soon see the rise of ‘digisexuals’ - people whose sexual appetites are predominantly satisfied by the virtual world.

Already, robotic sex dolls which move and talk and are ‘warm to the touch’ are being sold for in excess of £15,000, with companies vying to create the most realistic companion.

Pornography channels also now offer 3D content which can be accessed using headsets, while online role-playing games such as 3dx Chat allow people to interact sexually with each other using only avatars.

Sexbots are also increasingly on our screens, most recently appearing in Westworld, Humans and Ex Machina.
