You're right. There's a good reason for that. In a lot of ways she was still a kid emotionally throughout a lot of the series. She didn't begin to fully mature until she began to come to terms with who she is beyond being the Avatar. And getting the spiky haired monkey with the silly scarf off her back helped too. Some of the aspects you brought up were out of insecurities she largely worked through by the end of the series, and she'd likely be past them by the time she and Asami do become intimate.



That said, i still see Korra crying during her first time. She's probably not sexually active, might be nervous around Asami, and a lot of emotion would come out after they jump that hurdle.
