Don't worry if you're a little fuzzy on the subject matter, there are plenty of free guides on all subjects to do with female pleasure.
This is the perfect type of product to offer on Clickbank and market thru Clickbank with affiliates.
Once you have the book created, go find a bunch of other websites selling similar topic ebooks and propose a joint venture to sell your product to their list.
You may even want to sell the product outright to someone else.
