Charlotte Church is planning to write a "Lovers' Guide" to share her knowledge about relationships with the world.

The Crazy Chick singer came up with the idea after gushing about her love for rugby star boyfriend Gavin Henson.

"I never knew what it was like to feel this way," Church told the Daily Star. "Maybe I'll write a funky retro guide to good sex. There are so many unhappy women and lazy men out there."
