Los Angeles - Tori Spelling thought she had a "very, very good" sex life with Dean McDermott.
The True Tori star - who has children Liam, seven, Stella, five, Hattie, two, and Finn, 20 months, with her husband - was left stunned last year when it emerged her husband had cheated on her with a woman named Emily Goodhand, and she was surprised by his claim they had a "sexless marriage".
Speaking before the first episode of her new reality show aired - in which Dean told a therapist they slept together "once every two weeks" - Tori told Us Weekly magazine: "For having four children and very chaotic schedules, I thought we had a very, very good sex life.
"Dean said he didn't say that about the sexless marriage to her. It's 'he said'/'she said,' and I obviously haven't talked to Emily so I don't know what he said to her."
The former Beverly Hills 90210 actress also admitted she hasn't been able to bring herself to find out what Emily, 28, looks like.
She said: "I have written her name in my phone multiple times for Google Images and when it comes up, I can't look at it."
The 40-year-old actress got together with Dean, 47, when they were both married to other people - Charlie Shanian and Mary Jo Eustace respectively - and she says her own experiences mean she doesn't blame Emily for her husband's infidelity.
She said: "I was called a home-wrecker and a husband-stealer. I remember thinking, 'If this ever happened to me, I'd be pissed at my husband.'
"I have never held Emily Goodhand responsible. Dean did this, not her."
