Singer Robin Thicke sure isn't shy about his bedroom habits with wife Paula Patton.

In fact, the singer credits her as the inspiration behind his fourth album, Sex Therapy. "She's my sex therapist!" Thicke, 32, told Monday at his Svedka-sponsored New York City record release party at Butter nightclub.

Thicke, who wed his high school sweetheart, 33, in 2005, says the couple put his song lyrics into practice.

"We had a little bit too much sex therapy this summer," he jokes to Us, as the "excited" pair plans for the arrival of their first child next spring.

The singer says he welcomes his dad-to-be duties.

"We're preparing the baby room, painting rooms and picking colors," Thicke says. "Paula's kind of got the baby taste in the family. I'm just going to sing to it and cuddle with it and teach it how to play basketball and talk to girls."
