"In an interview by Scott for Metro Online, forensic psychologist and Leicester University lecturer Vincent Egan commented on doll-owners: “They need to think more about their relationships with the people they say they find sexually exciting,” he says. “Perhaps they can't fantasize easily themselves and the dolls help.” When contacted via email by this author to clarify his statements Dr. Egan said: Any prosthesis is an adaptation to a problem (or perceived problem). Some people may use sex dolls due to disturbed attachments; others may simply not have attachments to start... For men, who may program their sexuality to rely on appearance via pornography, the appearance of the doll will become the key to the eroticism, rather than the (sometimes) emotional, playful, dynamic and interactive physicality of sex (Dr. Vincent Egan, personal communication, July, 2011)."
