I think this song is about slut-shaming and the way our society makes women sex objects.
Nothing is provocative anymore
Even for kids
No room for imagining
'Cause everyone's seen everything
Here she tells about how all adds and everything kids and adults watch has something sexually in it - how sex is no more a intimate thing between two persons, but an object to sell things or get attention.
The "Question" part for me means, that you shouldn't just blindfold yourself and listen to what everybody says, because as she mentioned above, everything today is sexualized, and you should question what everybody tells you, because they may seem clever or kind, but they could still fill you up with nothing but crap. So question every opinion and make sure, you agree/disagree with it.
If history could set you free (from who you were supposed to be)
If sex in our society (didn't tell a guy who he should be)
'Cause all my life I've tried to fight what history has given me
The chorus is for me very much about slut-shaming and the woman as a sex object. In all history, the woman has been seen as a sex object, but also someone who had to dress proper, take care of house and kids and at the same time not being "slutty" (having sex with many guys). Even though feminism has done a lot of good stuff for the modern woman, the stereotype of a "good" woman is still something like this.
The next line in the chorus is about slut-shaming. Society has told girls, that if she has sex with who she wants and as many she wants, she's a slut. Society has made sex a bad thing. But why is that? Why does it make a difference if a girl has sex or none at all? On the other hand, if a guy has a lot of sex, he's totally cool. In that way, sex tells guys (or girls) how they should act and do to get accepted in society.
The last line in the chorus refers to Marina's personal opinion upon this - she doesn't care that history has set the woman in a stereotype box, and she'll do whatever she wants if she feels for it, and she tries to tell other girls to do the same.
If women were religiously recognized sexually
We wouldn't have to feel the need
To show our ass it's to feel free
Been there done that got the t-shirt
Sold my soul and yet the truth hurt
Tired image of a star
Acting naughtier than we really are
The next pretty much tells about the same as above. The first two lines tells, againg, about how the past has set the woman in this stereotype, and made women a sex object. The next lines tells about what's expected for a woman on the sexual side. On one hand, she'll have to be controlled and calm and "proper", and on the other hand, she has to be this wild sex object ("Acting naughtier than we really are" She directly tells us, how tiring it is to have this pressed down on your shoulders. She did try to be the classic sex object, but she didn't feel any pleasure of it, and therefore she began questioning the whole thing.
