Oz joins the school jazz choir to find a girlfriend. From a college girl he tried to seduce, Oz learns about sensitivity and that it is about asking girls questions and listening to what they say. He soon wins the attention of Heather Mena Suvari , a girl in the choir.

Stifler persuades Jim to set up a webcam in his room so that they can all watch Nadia changing clothes. Nadia discovers Jim's pornography collection and while half-naked sitting on his bed masturbates to it. Jim is persuaded to return to his room, where he joins Nadia, unaware that he has sent the webcam link to everyone on the school list. Nadia is interested in him, but he suffers premature ejaculation twice and is unable to complete intercourse with her.
