The second part of the book deals about amorous advances and sexual union, stimulation of desire, types of embraces, caressing and kisses, marking with nails, biting and marking with teeth, on copulation (positions), slapping by hand and corresponding moaning, virile behavior in women, superior coition and oral sex, preludes and conclusions to the game of love.
