Dath ilani learn fast, generalize fast, and get bored with a speed that would shock the more easily amused.  They overcomplicate sex because they have no choice.  They do their best to protect their kids from sexual spoilers so that young adults can have the joy of discovery and amusing stories to tell for the rest of their lives, and also that young adults don't exhaustively play out simple basic sex in their heads before having it, which, if they did, would lead them to learn-the-pattern-and-get-bored-by-it even faster.

Even Keltham of the +0.8sd, though, is able to spend a while just kissing Carissa without getting bored the first time he does that.  She is quite kissable.  Also snuggly.
