In human society, the phallus is considered a symbol of dominance and masculinity, and we tend to think that this idea has a biological basis. Science journalist Emily Willingham, talking about mating rituals and animal penises, shows that in fact nature had very different plans for this body and it was not created so that its owners would be endowed with any advantages. Tracing the "evolution" of the human penis, the author also discusses what we can do to deprive the phallus of its symbolic power, and comes to a simple conclusion: the penis was created "for love, not for war", for intimacy, not for intimidation. The book boldly touches on sensitive issues and at the same time is full of humor and irony, extremely entertaining and educational.
