Katie Holmes wants to have more sex with husband Tom Cruise.

(Although we can’t image why….)

Katie has a three-year-old daughter, Suri, with the pint-sized Hollywood superstar, but the actress has increasingly frustrated with the couple’s hectic schedule and nearly non-existant intimacy.

“Katie has become noticeably more miserable in the last few months. She finds it incredibly taxing to lead a life that revolves around Tom but that doesn’t include enough intimate time with him to be genuinely fulfilling,” a spy told Closer Magazine this week.

“She doesn’t just want to go to red-carpet events with him. She always feels like she’s competing for Tom’s attention.”

Friends are reportedly worried about the 30-year-old star, the source added.

“Everyone is worried that she’s close to breaking point. Katie spends most days alone looking after Suri. She’s a devoted mother, but it’s a lonely job. She and Tom have such separate lives.”
