Realistic sex dolls

By 2025, it is predicted the VR adult-entertainment business will be worth around $1 billion, making it the third largest entertainment industry after video games and the NFL. A combination of visual, sensual and intellectual elements are needed in order to create lifelike intimate sexual experience in the virtual world. Gadgets such as VR headsets, synched vibration of intimate parts and sex toys can help to make the whole experience as 'real' as possible.

This means we could soon be able to live out any sexual fantasy we desire without ever having to leave the comfort of our homes. "In these digital places, you can be gender fluid. You can be anything and anyone you want to be," Barber says.

"The idea of engaging in a space as an alternative self becomes really exciting. When it comes to sex, sometimes people are engaging in fantasy plays, and they may dress up as somebody, they will put on these fabulous avatars on themselves, and I think it's a marvellous time for people to just be something different if they want to be," she adds.
