This series of New Teen Titans was very physical and sexualized, even in the ordinary non-sexual interactions: lots of lounging about the pool together, hugging, flirtatious banter, clothes tattered in fights. And of course the Baxter magazine became more forthright about Dick and Kory's sex life than mainstream comics had shown before.
It may also have been a reflection of the times. By the mid-1980s young people had become aware of HIV, and attitudes toward sexuality swung back. Some people find Terry Long creepy now; back then he was innocuous.
