Humans could become addicted to sex with robots/dolls.

A lot of men in Asia and even America have now purchased sex dolls and robots to satisfy their sexual needs. This robots can moan at different pitches, come in different shapes, sizes and races making them the preferable choice for men who are shy of approaching women and men who don't want to be 'stressed' by humans.
Now according to an expert in Robotic research, Joel Snell, who is an American Research Fellow from Kirkwood College, humans could soon become addicted to this sex robots because they’ll offer great sex at any time of the day and night.
Another British academic called Professor Noel Sharkey, who is considered the nation’s leading authority on the morality and ethics of robots, says very soon sex robots will be dis-virgining young men and women.
‘Sex robots are accessible now and certainly [will be common] within the next 10 years,” he said during a speech at the Cheltenham Festival.
He said: “It’s not a problem having sex with a machine. But what if it’s your first time, your first relationship? What do you think of the opposite sex then? What do you think a man or a woman is?
“It will get in the way of real life, stopping people from building relationships with normal people.” “I think there will be an age limit,” he continued.
“Certainly there should be, but if your dad or mum had one, you could sneak in and use it.”
'There’ll be no need to form a bond with the robot, plus it’ll never be able to turn you down. People may become obsessed by their ever faithful, ever pleasing sex robot lovers,”  he told Daily Star. “People will rearrange their lives to accommodate their addictions.” People will also be able to tell robots exactly what they like between the sheets.
