A common theme in teen comedies is sexual exploration and first-time experiences, and just like Superbad, Sex Drive centres around the journey of lead character Ian Lafferty (Josh Zuckerman) to have his first sexual experience. Ian, a recent high school graduate, meets a girl known as "Ms. Tasty" online and boasts about his physical attributes, leading her to ask him to visit her in Knoxville, Tennessee, where she lives. Along with his two friends, Ian travels to visit her but runs into some trouble along the way, including his car breaking down, getting picked up by strangers, and going to jail. In the end, Ian realises that Ms. Tasty was using him the whole time, but he might just get his first sexual experience from someone he loved all along.
