Sex work would probably be less stigmatized in a currencyless society
Thinking about this because of a greentext I saw earlier complaining about OF models.
It feels like a lot of the stigma surrounding sex work in the modern day (that doesn't just boil down to misogyny/gender norms/religion) is based on the fact that selling intimate aspects of one's self places a set value on something that many see as sacred; something that shouldn't have monetary value.
Not to say anything about the economic validity of a society without currency, but I think that, hypothetically, if that were to exist, sex work would be less stigmatized since this would no longer be a factor. Those engaged in sex work would be more likely to be seen as doing it because it's something they are good at/enjoy, and less because it's an "easy" way to make money, as some think. It would also eliminate the fear of placing set value on social, non sex-work related intimacy (not that those fears were well-founded to begin with).
It really depends on the culture of the area, but yeah overall it'd probably be less stigmatized on average. It would certainly be stigmatized though—some people forget that many people consider sexual acts in general (that others can see, like posting pictures on the Internet, porn work, etc.) wrong in the first place. A lot of people online don't interact with these people a lot—not necessarily because they 'don't touch grass' but because these are often the people who chose not to be active in social media. When you consider that they see a woman posting a steamy picture of herself online as wrong, it makes sense why.
Many people have grown up with a very conservative (sexuality wise, at least) mindset, and that's just the way they were taught to see things.
I think that because of that, it's not unlikely that a large portion of people would still see person doing these things, even if not for monetary gain, as "sluts" or something similar.
