Needing Feedback on Idea

I am a writer and graphic designer...published monthly in an online magazine for creative journaling and artistic expression with photos. I have been told that I have natural writing ability and a very unique style. I have no formal training at all. I have a compilation of erotic letters which all include short stories....I would send my lover a fantasy story about us weekly...he would choose a "word" and that was what the story would be inspired by. I was tossing the idea of putting these letters in a book form along with tasteful black and white erotic photos. I think it would be very marketable especially for couples to read together. The stories are very sensual, imaginative and explicit thus appealing to both a male and female audience. I really would like some honest feedback...
