Finally, if Cap's virginity is supposed to make him a better soldier, shouldn't there be some evidence that the other soldiers (namely Bucky) are worse soldiers because they are willing to sleep with anything that is willing and has two XX chromosomes? Bucky and the rest of the Howling Commandos seem just as violent and bloodthirsty as Cap, just without his superpowers.
Well, Bucky does
get tortured, is unable to make an impression on Peggy, and then (presumably) dies, so his fate would seem to be in keeping with a Puritanical reading of the flick. As for the rest of the Commandos, sure, they're rowdy and macho, but they're also a straight-up boy's club; we never see any of them with ladies on their arm.
