The American musician - who has dated a string of famous beauties including Jennifer Love Hewitt, Jessica Simpson and most recently former `Friends` star Jennifer Aniston - is tired of being labelled a womaniser because it makes him feel guilty about dating.

He said: "I should be having sex with more girls. It`s crazy to me that in my head being 32 and dating women is going to get me into trouble."

The `Gravity` singer - who is as well known for his relationships as his music - stops himself from going out with more girls because of the constant public interest in his love life.

He said in an interview with the New York Times newspaper: "I can`t even explain to you how terrible that feels, that I equate dating a woman with punishment, shame, guilt, disappointment, reproach, reprimand, persecution. It`s a nightmare."

The musician has previously boasted about his sexual conquests online.

He once wrote on Twitter that he`d "slept" with nine science-fiction fans at a comic book convention and that he persuaded "dozens" of women to leave lipstick marks on his face so the paparazzi would think he had several girlfriends.
