I think the best way that i can describe this book comes from a particular scene (minor spoiler, its really just a line though, and this isn't a novel or anything w a plot so,) where the author mentions "reading your fave sex scene or some homoerotic Harry Potter fanfiction" and underneath that line is a suggestive illustration of Harry and Hermione, hermione on her hands and knees, and harry behind her saying "we can do whatever you want"
now, the reason I think this is the perfect summation of this book is because the author makes some surface level effort to include queer people ("homoerotic fanfiction") and then seems to immediately forget it and go back to being extremely heteronormative to an extent that doesnt even make sense (the image she draws becoming heterosexual for seemingly no reason at all). This is a consistent pattern in this book. In the section when she talks about genitalia, she has a small blurb about how not every woman has a vagina and not all people with vaginas are women, and then immediately moves on to "and here is a section about penises and i will only refer to them as male, and talk directly to men about their penises" which genuinely gave me whiplash.
Overall this book seems to try to be inclusive and critical of modern pop feminism, but it fails spectacularly and is just extremely unaware of the fact that it IS modern pop feminism in every way.
but, to end on a positive note, the illustrations are definitely great, and I do think it's somewhat of an entry point for cis women who experience attraction to cis men to start their sex positivity journey, but it very much should not be anywhere near the last stop on that journey.
