Man Not Superman is a delightful short story by Jonathan Goldstein. It's written in the first-person perspective by the ordinary guy who dates Lois Lane after she breaks up with Superman. The narrator struggles with feelings of insecurity and inadequacy as he tries to fill the void that Superman left in Lois' life.
