And I think Tori Valentine basically covered it all!
I will say that tons of civvie women in the US don't shave anywhere, and it is only rare to see women with body hair in magazines, media, mainstream porn, and the hobby. I have loved my natural body hair since I started hitting puberty and explored my sexuality in my late teens with my body hair still on my body. I did start shaving when I became a provider because I made a false assumption that I would not find clients if I kept my natural body hair, that it would make me a "freak", that only rare/extreme fetishists would be interested, etc.
For me, the decision to go all-natural was about a return to what felt good for my body and to what makes sense in the context of my civvie life. I love to go skinny dipping with my friends in nature and all my friends keep their natural body hair, so I did not enjoy being shaved and bare next to all of them and truly longed to have my natural hair back. My girlfriends are pretty open-minded and know what I do got a living and when they used to ask me how I liked it, I used to say that the escorting was easy and natural for me but the hardest part was shaving off my body hair. Now that I have eliminated that, and realized that plenty of men enjoy women with natural body hair, I realize that what's a trend is the shaving. It's perfectly natural for men to enjoy women with body hair when given the option. My consistently-full schedule when I tour the country is definitely proof enough of that for me.
I *do* have civvie friends who would love to be providers but who will never be willing to shave off their natural hair. So now that I know that the market will support women like this in the industry, I do encourage women to try it. So I won't be surprised if you continue to see more women with hair venturing into this side of the industry as they see more examples of hairy women who are wildly successful.
Just for reference, in both California and Europe, it's very common for women to keep all of their natural body hair. That's TODAY, not 50 years ago.
