Exploitation/ oppression

[Gladysthesphinx]

In feminist terms, is there a difference between oppression and exploitation? Does exploitation mean treating women as a resource (extracting something from them: love, domestic labour, children) whereas oppression is keeping them down (for the purpose, generally of exploiting them)? What’s the relationship between the two concepts?
Also, can anyone recommend a good introduction to Marx’s thoughts about exploitation of women as a biological class?

It was really Engels who was most aware of the way capitalism used women as a class. Have a look at his The Origin of the Family, Private Property and the State.

Thanks!
