As long as you are genuinely happy and safe in what you do then it's your choice.
Interestingly, many (the majority?) of feminists have moved beyond the idea that prostitution is derogatory to women. I used to feel that men who 'used' prostitues were abhorrent and that prostitution was wrong because it was using a woman's body as a commodity that could be sold to the highest bidder.
It was internet posters who made me think through my views properly actually. It seems many strippers, prostitutes and other sex industry workers chose their job as a positive affirmation of their womanhood and a show of confidence and ownership of their own bodies.
A couple of quotes I've dredged up from another forum via the search function:
"In my opinion, banning the sex industry on the grounds of 'feminism' is completely counter-intuitive. It implies that sex, sexuality and the naked human form is something to be guarded and kept hidden, because it has the power to shape culture and politics. Sure, you can dress it up and say that strip clubs, porn etc are 'degrading' to women, but implicit within that is the belief that sex and open sexual expression are innately degrading acts rather than the free expression of basic instincts. Sexual expression is only as 'wrong' or 'degrading' as the person witnessing it believes it to be.
The idea that the naked female form, even one performing sexual acts, is something that has the power to change culture for the worse only serves to give credence and power to the misogynistic ideals of old: that sexuality is something to be expressed behind closed doors, between monogamous lovers."
"When people perpetuate the idea that being naked or using your body/sexuality for monetary gain immediately turns that woman into a sexual object who deserves to be objectified, they effectively excuse misogyny. Shutting down the sex industry to reduce the objectification of women does nothing to address the root of the problem - it doesn't challenge the belief that women are sexual objects or that it's OK to think that sometimes, depending on what the woman is doing or wearing. It says to those people 'porn/stripping make it easy for people to objectify women, so we're going to remove that temptation completely'. Ergo: 'objectifying women is only natural when they're in certain situations, and we want to stop that, so we'll stop them from entering those situations completely"
I don't think I agree with that viewpoint but just saying, it's out there and pretty valid.
