Harry Potter star Daniel Radcliffe is refusing to name the woman he lost his virginity to at 16 because she was much older than him.

The young actor makes the big reveal about his first time in a new Details magazine interview, but he's not revealing who his first love was.

Now 19, Radcliffe insists the age difference "wasn't ridiculous," but "it would freak some people out."
