Rocker Chad Kroeger has revealed that his sex life with fiancée Avril Lavigne is great although it's strange to be in a relationship because he's used to being a single man on the road.

In a new interview with Men's Health magazine, he explained that while things in the bedroom are great he's worried that Lavigne might ask questions about some of his band's more risque lyrics as he wouldn't want to explain them:

"I don’t think my libido has changed. I just think that my rolodex has been confiscated. And I’m okay with that. If a naughty Nickelback song came on, my fiancee would probably ask who it was. She’d be like, 'Who’s this? This is good. I like it."

"I’m terrified that some day she’s going to listen to some of the things I’ve written, and I’m going to have some explaining to do. There’s going to be a whole question-and-answer period following that one."

Meanwhile, Lavigne attended a Halloween party in Hollywood last night (October 31) dressed as a sexy sailor and tweeted a few photos of her suggestive costume: "Trick or Treat... Happy Halloween! Hope everyone had a good safe night. Anchors away!"
