Sure, the Northern Tribe might have benders, but they have such a different culture/identity around bending compared to the South. We see in Hama's flashbacks that the Southern Tribe had male and female benders at the helm, fighting equally, learning the same things, sharing the same tactics. They weren't left behind as strictly healers or defenseless women given a man's gift, they were strong.

And the thing that separates Katara and Aang's stories being the last benders of their nations is that Aang remembers what it means to be an Air Nomad. There are obviously blind spots because of how young he was, but Aang knows the customs and the culture and spiritual practices. He was able to pass those down to Tenzin and his grandchildren, he was able to start the process of rebuilding what was lost.

But Katara? She was even younger than Aang was when the Southern waterbenders were eradicated. There are Southern practices that are most definetly just... a fractured part of history because she never got to experience them. There are ways of hunting, of building, of navigating the waters, ways of healing, probably even spiritbending, that are simply lost to time.

And maybe her grandmother can clue her into it, memories from a nonbender living aside benders, but it's not the same. She didn't get to hear it from the waterbenders, she didn't get to learn from a Southern waterbender, she doesn't even know what to rebuild because it was never something she was versed in.

That's why The Puppet Master is such a heartbreaking episode. Because Hama could have been the Southern teacher Katara clearly wanted, she could have shown her more, but ended up passing on her legacy of Bloodbending. And on the inverse, I can't even fully call Hama a villain for wanting Katara to know how to bloodbend, because the ache of thinking you were the only one left for so long, the rage against a Nation known for destroying nations, would've driven anyone insane.

Meanwhile this was what various medical professionals in that reddit thread had to say about it.

^ this is. The ONLY dialogue in the entire game where Morrigan outright claims experience of sex, per the wiki. In my opinion, the comment at The Pearl is directly related to these banters with Alistair and Leliana, which suggests the "experience" Morrigan is talking about isn't sex she had, but instead sex her mother had that she, unfortunately, witnessed or had described back to her.

Apart from that, here's the only companion dialogue that implies she might maybe know some stuff about sex, which… you can take or leave as being experience-based knowledge:

Notably, the second Leliana one is cut dialogue, but we'll take it into consideration cuz why not.

To me, this reads as her being mean to Leliana and trying to make herself Being Sexual as opposed to Being Romantic her "winning quality" in the weird catfight Gaider and Chee had to get in there for ??? reasons. There's some Madonna/Whore stuff going on in there that, frankly, deserves its own post. (And, as the link shows, has been extensively in its Andraste and the Witch tag set. Go look at its posts, the posts are fantastic.) But the point here is that the above dialogue doesn't necessarily imply Morrigan has ever actually had sex before the Warden. It implies that she thinks having sex with someone is a means of controlling or manipulating them. Which. Given what the last chunk just said about her mother's use for sex, can you blame her for arriving at that conclusion?
