Near the end of the movie, we learn that Larry is a virgin. But in the first movie, he makes a statement that seems to indicate otherwise. When Bernie's girlfriend happily comes back downstairs after apparently sleeping with the corpse, a surprised Larry comments that he gets yelled at when he just lies there. Although it could be a made-up boast to convince people he has had sex and is not a virgin, it seems unlikely because he would also be admitting to "just lying there" during sex, which isn't much of a boast.
