"The analogy I want to use is that gendertropes are like a standardlibrary, but I don't know if Leareth's world has programming languages... they're like a preamble that anyone can include at the start of their autobiography, that will make some chapters shorter, because the preamble already explained what you'd otherwise have to explain yourself."
"Let's say you've got a desire disparity, a very standard sort of problem that arises in a relationship where one partner wants to have sex twice a week, and one partner wants to have sex every day. The question you want to ask is not 'What sort of thing happens on average, what sort of solution usually works, in a relationship where one person wants sex twice a week and one person wants sex once a day?' Instead you want to ask: 'What sort of people are we, as individuals and in our expression of our own sexualities, who have found ourselves this scenario?'"
"If you've got a 15-year-old male with a high sex drive who's into older women, in a relationship with a 45-year-old woman who thinks he's cute but doesn't have that much time for him, the standard first-thought solution is for him to form a harem with three women like that. On the other hand maybe you've got a 30-year-old woman with the 'desperate demislut' gendertrope, where she's got a very high sex drive and constant horny thoughts, but her mind is extremely picky about which men she can express her sexuality with; and she's found herself just one man, who unfortunately isn't as horny. Then it makes more sense for him to consider implanted testosterone pellets."
"The first culture I found myself in, after I got isekaied from a plane crash, was one where everyone just had one concept of what it was like to be a man, or what it was like to be a woman. They didn't even have the concept of it being different on average when a 15-year-old man dated a 45-year-old woman than when a 45-year-old man dates a 15-year-old woman, because they hadn't formed the idea that on average 15-year-old men are different in their expressions of sexuality and relationships from 45-year-old men. They had the differences, to be clear, what they didn't have was the concept. They just had one ideal for what men were supposed to be like, and one ideal for what women were supposed to be like, and they believed every male and female was supposed to live up to that. I explained the idea of gendertropes to them, though, and that fixed most of their problems."
