Tori Spelling and Dean McDermott are dodging the cheating allegations, but new reports say the couple has been in trouble for years.

According to Hollywood Life, McDermott reportedly wants to be intimate with his wife on a daily basis, but Spelling isn't into it.

"Dean wants sex from her 24/7," a source told Hollywood Life. "Their sex life when they first hooked up was wild and kinky. Of course, they didn't have children and were very uninhibited."

McDermott would also allegedly criticize Spelling if she didn't "perform"  in the bedroom.

"Dean would always throw it in Tori's face that their sex life wasn't as hot as it used to be," the source added. "Well, how could it be? They now have four children, and Tori would stay up with Finn all night when he was fussy. The last thing Tori would want to do is have sex, and yet Dean would be ready to go! He even accused Tori of paying more attention to their children [than him]."

McDermott allegedly had an affair with a 28-year-old Canadian woman named Emily Goodhand while visiting Toronto, according to RadarOnline.  Spelling reportedly has never fully trusted McDermott, even though the couple has been married for seven years.  Spelling allegedly isn't acknowledging the cheating rumors because she believes her husband did have an affair.

"It's all a calculated plan on Tori's part...she is refusing to comment on the cheating rumors publicly, even though she believes Dean did cheat on her," an insider told RadarOnline.  "Tori is obsessed with having a picture perfect family, and thinks it's a big part of her image. Commenting or addressing the cheating would taint that image. Things are very tense in the house right now, and Tori is making Dean's life hell."

"Even though she is trying not to fight in front of the kids, it's impossible," the insider added.  "She has been crying and screaming at Dean, and saying he has ruined everything, including Christmas."
