But if Gwen was willing to have sex with Norman under such flimsy reasoning (she was attracted to him, father figure, moment of weakness, etc.) why is there no evidence (and the book don't even seem to hint at it) that she ever let Peter get that close to her. Even by the timeline the author of the article is using to shoe-horn the story into previously established Spidey stories, Gwen realized her mistake with Peter and got back together almost immediately (as if giving her virginity just a minute ago to Normie never happened - and yes I do believe she was a virgin based on various things the Marvel/Joe Q have stated about the storyline) and apparently she was able to go to Europe, have kids, come back without looking any different at all, act like everything was "normal" with Peter (and in the original 1960s story that's how she acted) as if the Norman thing never happened and then still claim to love Peter (who she apparently never let get as far sexually as she let Norman).
Let's face it, despite what some - few - would say this is NOT a story that deepens Gwen's character. It does not make her slut, I'm not saying that but it does nothing but make her either stupid or (in her dealings with the man she supposedly loved and wanted to raise Osborne's kids with but not enough to have even a one-night stand with like she did Normie or to even tell him anything about it) a dishonest hypocrite.
