Written as a follow-up to his best-selling book She Comes First, Passionista is sex therapist Ian Kerner's down-to-earth guide to male sexuality.

How can you have the best sex? How do you keep the spark going? Why do we struggle to communicate what we want?

In Passionista, Ian Kerner explores male desire and what turns men on, rooting his advice in human biology and wider studies of human behavior.

Through expert science lessons and getting down to the finer details, Kerner looks to revitalize the sex lives of men and change the ways men think and act outside the bedroom.
