It'll be curious to see how Mera reacts to Aquaman's various conquests, most of whom are still hanging around Atlantis, since none of them have books of their own. Just ask Bill Clinton. And you really don't want me to go into the menage a trois scene that was played for laughs. And let me reiterate that DC is not unique in this regard. The Savage Dragon over at Image Comics has an extremely active night life, and of course, Marvel's Iron Man has a girlfriend on every continent.
Sex is a part of life, and therefore a part of good storytelling.
And, let's face it, the implied sex in comics is nowhere near as overt and blatant as what you see on an average network television show. In fact, we should convince ABC to do Young Heroes In Love.
