Kylie Minogue is easily bored in bed.The Australian pop star - who is dating French actor Olivier Martinez -admits she is a highly sexual person and enjoys a lot of variety in the bedroom. Kylie, who this year overcame breast cancer, said: "Sex is the most natural thing in the world. When I'm in a relationship, I like lots of it. I like to be swept off my feet. But I do have a very low boredom threshold."Earlier this year, Kylie confessed to having steamy phone sex sessions with Olivier.The diminutive singer admitted the smitten pair have such hectic work schedules they have to resort to dirty texts and racy conversations to keep their love life going.
