Veteran actress Joan Collins is disgusted by teen magazines which destroy the innocence enjoyed by young girls. The DYNASTY star, 72, has hit out at the graphic and distasteful publications, which she believes force girls to grow up too quickly by teaching them about sex before their time. She says, "I think a lot of children are losing their childhood because so many magazines for girls are so graphic. "I think that's a great pity. Children know too much. "I never saw a naked man until I got married no sex before marriage I'm really kind of private, I never discussed things with the girls. "It's hard to understand today."
