Tiptoes (2003)

Carol: Have you ever been involved with a little person sexually?
Steven Bedalia: No, just kid's stuff, you know? Y'know, all the kids would come over, we'd sit in a circle, play doctor and that kind of thing. Couldn't have been more than ten or twelve, so that doesn't really count.
Carol: So you had a circle jerk with a bunch of little people? I would have loved to see that.
Steven Bedalia: You would like to see that.
Carol: Yes, I would.
