Speaking to the Daily Mail, Doctor Who actress Karen Gillan revealed how she thinks Doctor Who should never show any sexual scenes, especially not in the Doctors TARDIS, jokingly suggesting they could release an over-18s DVD.

'Oh God no, it's a family show. Perhaps there might be a DVD for the over-18s, you're not going to see any of that funny flirty business in the Tardis. River Song was conceived on the Tardis. It’s kind of insinuated, but never actually said. They did well to have sex because Amy and Rory have bunk beds on the Tardis. The Doctor finds it funny because it’s a bed with a ladder.'
