I was fourteen when I first watched "The Survivor" and I was certainly well aware of what being gay was, along with all the sterotypes that many people subscribed to. At no point from the onset did I ever get the impression that the Vendorian (as Carter Winston) could be trying to suggest he might be gay to Ann Nored. Now if you saw this episode for the first time decades after its original broadcasts then it's possible you might get that idea, but I think that has more to do with what one could be projecting onto the scene rather then what is actually there or intended by the writers.
