When does no mean no?

The Maryland Court of Appeals heard arguments Tuesday morning in a rape case that will decide what happens when consent for sex is initially given and later withdrawn.

From the Sun article linked above:

The victim, who had met Baby that night, testified at the trial that she told him that “as long as he stops when I tell him to” she would have sex with him.

As he began, she told him to stop because he was hurting her, but he kept going for five or 10 seconds, she said.
