Hooked: The Brain Science on How Casual Sex Affects Human Development explains what happens inside the brain when people engage in sexual activity, and why it matters for emotional health and relationships.

Drawing on accessible scientific research, the authors show how sex triggers powerful brain chemicals that create emotional bonds between partners. These bonds can strengthen long-term, committed relationships, but repeatedly forming and breaking them may contribute to depression, numbness, and difficulty connecting deeply in the future.

The book also addresses the neurological impact of pornography, describing how repeated exposure can reshape neural pathways, affect expectations, and influence real-life intimacy.

Hooked is written for readers who want to understand the hidden brain-level consequences of casual sex and to make more informed choices about relationships, commitment, and sexual behaviour.
