This 15 minute TED Talk is great to use during the Personality Unit. I use this opener as an avenue to discussing ourselves and our personality types. He discusses introversion and extraversion during his talk and he also looks at trait psychology.
There is one point towards the end of his talk where he discusses a study and how the numbers of sexual acts/encounters vary based on if one is extrovert and introvert. I deemed it fine for my class use since we discuss sex in other units and it is only a brief portion of the talk.
