A City trader has denied raping a young woman after a cocaine and champagne-fuelled office party, saying he thought she was crying because of the size of his penis.

Daniel Green, 26, allegedly attacked the woman, in her 20s, after she had curled up to sleep under a desk in the early hours.

Giving evidence at the Old Bailey, Green said that he had trouble having sex with women because of the size of his penis, which would sometimes cause pain.

Green had told jurors how he had met up with the woman, who cannot be identified, during after-work drinks which went on to the stockbrokers' offices of StratX, near Monument.
