Erika & Matthew think the world of sex is fantastic. Using comedy, real-life experiences, and research, they create some the best educational, informative, sex-positive comics around. (The puns are an added bonus!) In this fourth volume, they tackle a variety of interesting topics, including sex toys, what to expect at a gynecologist visit, the question of "what even IS sex?," and STI testing. In addition, an entire third of the book is dedicated to showcasing guest cartoonists with their unique experiences and perspectives about sex, covering topics from body image to fursuiting to pegging, to name a few! Every volume of Oh Joy Sex Toy is a stand-alone adventure into the world of sex, so whether you've collected the other volumes or not, this book is a great fit on any shelf!
