You've got to realise that the Dune books past Children of Dune came out at a time when books like Gravity's Rainbow were being published. The standards for what was pervy in literature were really being pushed further than ever before by postmodernist authors. So when Frank Herbert is saying that he's not a pervert that would write about certain things, it's in the context of being compared to other popular works of the time.
