She's sex positive as fuck
Kathryn exudes sex and unabashedly loves it. And who are we to judge her for it? In fact, she should be praised for it. She's probably crossed a lot more off her sexual bucket list than we have, including dabbling in lesbianism with Cecile (and probably others, TBH). Kathryn's game for anything, except missionary of course. That's sophomoric and pedestrian. She was open about how much she loves sex, but she wasn't going around broadcasting it for validation or attention.
