A MAN accused of sexually assaulting a woman said he could not have raped her because he suffers from impotence if he is drunk.

Mohammed Shahjahan, 27, of Slaymaker Close, Headington, Oxford, denies rape and assault by penetration, while Feizal Ali, 25, of Howard Street, in East Oxford, denies assault by penetration.

Giving evidence, Shahjahan said he had previously had a sexual relationship with the woman — who cannot be named for legal reasons — after first meeting her at a house party in 2008 but did not have sex with her on the night.

A mobile phone picture showed him lying on top of the woman. He told the jury he could not have had sex adding: “I know my body better than anyone. When I had sex with her last time I used condoms and there were none available on this night.”

When asked by John Reilly, defending, why the victim’s face was covered in the photo, Shahjahan said: “She didn’t want her face in the picture.”

The trial continues.
