The Dune books aren't that weird about sex early on, but this scene I literally had to stop and laugh at how absurd it was.

“do you have a wall-climbing fetish?”

This is the one lusty thing I have that won't get fulfilled with porn, nor IRL, since I'm already married.
I used to go climbing, and never got with anyone in the hobby since it's always "don't hit on women in exercise places"
