The actress - the first Indian cover girl in Playboy - opened up to her followers on Twitter about her history.
"In the past, on various occasions, I've had sex for money. Out of all my past experiences of paid sex, there's not a single one that I remember having indulged in out of free will," she wrote.
"But ever since I got back from LA in July this year, there has been a shift in my level of consciousness. I now understand that I cannot claim to be 'free' and continue to make choices and decisions under obligation."
Chopra also shared a series of recent nude images with her followers on the social networking site.
The star, who has appeared in a number of Bollywood B-movies and was a featured artist in commercial films like Dil Bole Hadippa, went on to say: "I enjoy being bold. I enjoy oozing sexuality in still pictures and in moving visuals. I enjoy being a tease. I enjoy sex when it is the end result of an uncontrollable lust and/or attraction."
However, she clarified that her spiritual beliefs mean she has decided to no longer accept payment for sexual relations.
"Sorry to disappoint you but I'm no longer available for paid sex," she wrote. "Why? Because I've come to realise that I derive no pleasure or joy out of physical intimacy that is pursued out of obligation (mental/emotional/financial or any other kind).
"I now believe that there is in infinite power and infinite intelligence within each one of us and if we persist in having a child like faith and a child like belief in the powers of the spirit/the subconscious mind, and then there shall be no lack of tangible and intangibles riches in our lives.

Chopra's Playboy cover - in which she is described as a 'Bollywood Goddess' - hits the stands in November.
