Jake Gyllenhaal urges his sister to do onscreen sex scenes.The actor, whose sibling, Maggie Gyllenhaal starred in steamy movie 'The Secretary', has confessed although he cringes when he sees her nude in a movie, he thinks it is empowering for a woman to strip for the camera.When asked how he feels about seeing his sister in a naked scene, Jake confessed: "It's great I'm sort of saying, 'Yeah, it's right. Show them what it's all about!' "But as a brother, I still hide my eyes and I still say, 'Oh, my God!' And I know she does too when there are love scenes that I'm in"He added in an interview with Movie.com: "Then again your parents did something to have you, so even though you don't want to think about it, it does happen, you know?"
