Sienna Miller lost her virginity at 16.The 25-year-old actress had her first sexual experience in her bedroom, because her mother insisted she experimented with her boyfriend under her roof.She said: "I had my first serious boyfriend when I was 16 and my mother made sure I brought him home. "She didn't want me doing it outside and would say, 'I'd rather you did it in my house if you're going to do it at all.'"It was a very open household but I only brought home guys I really liked."My mother was very warm and accepting of anything we got into as children."Sienna recently revealed she was determined to make the sex scenes with her 'Factory Girl' co-star Hayden Christensen as realistic as possible.
