Why does she do it?

Mr. Littlejohn of the Daily Mail offered a fascinating theory about the prime minister in his last column before his Xmas break. She’s a political masochist, who enjoys flying round Europe being told No! and being humiliated by the stroppy male** gits running foreign countries.
    The louder the No!, and the bigger the rebuff, the more she loves it. The theory certainly fits the observed facts.
    ** Angular Mherkle, being an east German, can be identified as male in this context.
