As far as DC, I'm pretty sure neither Superman or Wonder Woman were ever shown as having sex until Superman got married, and Wonder Woman continued to not be so portrayed. Then, when Phil Jimenez was writing her series (during which she had also gone without a serious love interest for over a decade) he introduced the love interest Trevor Barnes, and raised this big stink about how he was going to be the first to show Wonder Woman as having sex, presumably just by showing the two naked in bed together. However, looking up all of this info in news archives, it's all about how he SAID he was going to do it. There's nothing about it actually happening, so it seems like it never really did.
Then, when Greg Rucka was writing her series, he stated that he was going to introduce the idea that Diana had had relations with her fellow Amazons on Paradise Island. Which seems weird since she was the only child on an island full of grown-ups and they all watched her grow up.
Then, after the 2011 reboot, they showed Superman and Wonder Woman knocking boots with hats off.
So I guess my question is, did Jimenez and Rucka follow through on these? I can't find anything concerning Trevor Barnes? Besides Superman and Steve Trevor, is Wondy shown taking any lovers?
