Legendary lothario SIR Tom Jones' libido is diminishing with age, but the singer likes his new relaxed attitude to sex. The Delilah hitmaker admits his bedroom behaviour has severely slowed since he turned 65 last June (05). However, the star insists he is comfortable with the change. He says, "The older you get the less sexual drive you have. But that's probably a good thing. I'm not so frantic all the time, I've kicked back."
