It's a serious dilemma I've pondered sometimes. It's advised to separate audiences, but I love (really really really I love) all my followers and readers so much that I don't want to keep my non-NSFW writing from them.
I've felt unworthy of writing SFW books because I'm an NSFW artist, but I also desperately want to write beautiful stories. But I'd probably have a hard time.
I just don't know. I want to write funny and romantic things, but if people who don't know my NSFW artistic side see it, they might hate the book for that. I wonder if it would be okay for an NSFW artist to publish SFW books.
