Swansea-born MP Nigel Evans told police was 'staggered' at being arrested on suspicion of sexual offences, Preston Crown Court heard.
Jurors in the former deputy speaker's trial, heard transcripts of his police interviews at Preston Police Station following his arrest in May last year.
The 56 year old is alleged to have raped a man in his 20s following a dinner party at the MP's home in Pendleton, Lancashire in March 2013.
During interview, Evans said: "Did I have sexual contact with him, the answer is yes. Was it non-consensual, the answer is no."
He told police the young man had intended to stay in the spare room, but after the other guests left they began "caressing and kissing" downstairs and when Evans went upstairs the young man asked: "Should I follow you?"
Evans said: "As far as I was concerned everything that occurred was consensual. I'm somewhat staggered by the allegations he is now making."
He denies one rape, two indecent assaults and six sexual assaults. The trial continues.
