A man accused of murdering his wife told detectives they were working on the physical side of their relationship because she wanted more sex.
Robin Garbutt, 45, denies murdering Diana Garbutt, 40, above the Post Office in Melsonby, North Yorkshire, in March last year.
Mr Garbutt told officers he attended Relate sessions with his wife and that she wanted to have more sex.
The jury has already heard Mrs Garbutt struck up relationships with three men.
The prosecution at Teesside Crown Court claims Mr Garbutt, who had £30,000 of credit card debts, murdered his wife in the early hours then pretended an armed robber killed her and fled with cash from the safe.
The court was told detectives questioned Mr Garbutt about the state of his marriage after he was arrested.
He told detectives: "We did not have enough sex. We both would like more.
"It was something we were always working on. It did upset Di at times but we did discuss it."
Mr Garbutt blamed his hours working in the shop and added: "Having sex above the shop in the morning, it's not the ideal place."
He added: "Even though we definitely loved each other she just thought we didn't have enough sex - she would ask me 'Do you find me attractive?' I would say 'It's just I'm tired'."
He agreed that they had discussed her moving out and renting somewhere else in the village, but denied it was so she could sleep with other people.
"I was under the impression it was to give us more space," he told police.
Mr Garbutt was asked by the officer: "Has there been a point where you felt you were losing Di?"
He replied: "No, never. Never."
In a final interview, Mr Garbutt denied killing his wife, saying: "I have never hit Di and I never would."
The trial continues.
