I was looking for a book as a present for someone today. One possibility was one called ‘The Intimate Enemy: Winning the War with Yourself’. OK, let’s not dwell on why and for whom and all that. The point is that I searched in Amazon (support your local bookshop and all that). They didn’t have the book but gave the closest matches.
First up was ‘Intimate Invasions – The Erotic Ins and Outs of Enema Play’. Do you reckon this would do?
