I've heard that the Hal being a womanizer is pure retcon. Number of girlfriends I count Pre-Rebirth are:
Carol Ferris Arisia Kari Limbo Olivia Reynolds Power Girl
....which if my numbers are right or even 1 or 2 off, are still average compared to the some of the other DCU men (clark, bruce, Dick, Kyle, all have had 3 or more s/o's).
