Question: why is padme older than anakin?
Answer: In 'The Phantom Menace' (set in 32 BBY) Anakin is aged 9 and Padmé is 14. He turns ten during the film. By the time of their (sexual) relationship in Attack of the Clones, (set ten years later, set in 22 BBY) he was 19 and she was 24 so the age-difference was just 5 years.
