Actress Keira Knightley thinks having a penis is "convenient". In an interview to The Guardian, the 33-year-old actress insists she's never wanted a penis she does think it's handy to 'penis up a tree', reports femalefirst.co.uk

"Almost every character I've played has tried to break out of that image of femininity," Knightley said. She added: "That's why I like period films, because it's such an overt cage you put the woman in. That's always something I've really identified with. I feel like I sit somewhere else.
