I had an argument with a friend of mine over the heroes who most "got around" with the opposite sex more in the Marvel Universe.
To our offhand knowledge (and disregarding the crazy relationships in the X-verse), we narrowed it down to Spider-Man, Daredevil, Iron Man and She-Hulk.
Then, we further considered that Spider-Man's married and his past relationships have all been with normal women. DD suffers from chronic "dead/unstable girlfriend syndrome" (some might relate it to Women in Refrigerators), so it became a contest between Iron Man and She-Hulk.
With the more recent revelation of the pair's "debriefing" in a somewhat-recent issue of She-Hulk, who's got more nympho-nanites in their blood?
(And also, if anyone could supply a list of who they've each been with, thanks.)
