I recently read an article on psychology site Psyche about a man who calls himself Davecat and describes himself using the even more unusual labels “robosexual"and “iDollator”. He prefers the company of life-size dolls to that of human partners. 

According to the article, robosexuals are eagerly awaiting the arrival of sophisticated sex robots: talking, walking dolls that converse with their  owners, discern what their users  want, and happily give it to them. ..
