Sienna Miller lost her virginity at 16

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.
She said "I believe that there's nothing worse than seeing a sex scene where
someone's got a T-shirt on because it's unrealistic. So I think that if
you're going to do it, do it.
"I watched it thinking, 'Oh my God, my dad's going to see it!' But it was
relevant to the story in that it's a movie about the 1960s, and sex, drugs
and rock and roll were a big part of that."
The scenes are so explicit it was rumored that the actors actually had real
sex. Sienna has strongly denied the allegations.
In other news, Sienna Miller passionately kissed Bryan Ferry's model son, Isaac Ferry, at
the BAFTAs after-party.
Blonde Sienna, arrived at the ceremony alone but was later seen getting
cosy with the Roxy Music legend's son at London club Boujis where they
partied until 5am.
A source told Britain's Daily Mirror newspaper: "Sienna was really hot for
her new man. They were holding hands and he was whispering in her ear. There
was a lot of chemistry between them.
"They moved into the back room that was cordoned off for select BAFTA
guests. They were kissing until 4am before coming out and joining the rest
of the party.
Isaac, 21, and Sienna first met when they were being photographed at the
same studio.
The actress is said to have immediately clicked with Isaac, and was keen to
introduce him to movie mogul Harry Weinstein at Sunday night's party. But
Isaac played it cool and flirted with other guests.
A source revealed: "At one point Isaac was looking over at this gorgeous
model and Sienna looked a little jealous."
