He said he was “respectful of his wife’s desires and refusals” but “also had fantasies about swinging” and “got pleasure” from seeing his wife undergo sexual acts that she normally refused.
A psychological report submitted to the court suggested Mr Pélicot displayed a tendency towards “paraphilia” – sexual arousal in atypical situations – and also “somnophilia” – an interest in having sex with sleeping partners.
This made him a “very caring and much-loved grandfather by day” but “a rapist at night”, psychologist Bruno Daunizeau explained in the report.
“During the day, you can be normal, and have another face at night,” said Dr Daunizeau, prior to referencing Stevenson’s Jekyll and Hyde creation.
Marianne Douteau, another psychologist, told the court that Mr Pélicot still felt his life could have carried on as normal, despite the crimes he has admitted to.
She agreed he had a “split personality” arguing “that he is a patriarch but he is also irresponsible and manipulative”.
“Behind closed doors he does not respect limits,” Dr Douteau added.
Mr Pélicot, who has been remanded in custody since his arrest in 2020, was considered too ill to give evidence on Monday, so will be cross-examined by prosecutors later in the week.
Detectives have listed a total of 92 rapes committed by 72 men, 51 of whom have been identified and charged in France’s biggest rape trial.
Mr Pélicot has admitted to drugging his wife and inviting strangers to abuse her over a decade.
Fourteen of his co-accused have admitted to rape.
But 35 men – from all walks of life – deny that they forced themselves on Ms Pélicot while she was unconscious, claiming that she in some way consented to libertine sex.
