Melissa Gira Grant wrote in her book that she had experience within the industry, but still managed to go the whole way through without once mentioning anything to do with her own work. She does the same in interviews/events as well, focussing on decrim and deflecting any questions about her own involvement, but still making it clear that she isn't a stranger to this. I do understand where your reluctance to mention it comes from, but ultimately I think it would help us and the movement more than it hinders you. If at the end of all this you decide that coming forward about your involvement is not worth it, then you don't truly want to write a book about sex work. I'm going through a somewhat similar thing, contemplating any likely research I end up conducting in this field, without actually mentioning my own involvement. I came to the conclusion that should I ever conduct such research, I would do it whilst being totally honest about my sex work, if only to make it clear where any biases lie (in the name of integrity). If I never get to the point where I feel free to out myself, I won't do the research.
