filibustering as a sex habit:
Well, a friend of mine used to do something like that - he got high on things he read and would want to transmit his turn-on to people in a kind of bowl-over, speaking-in-tongues effect (and he did come from an evangelical background). So he'd read stuff from books, fairly complex texts at a teeth-clattering speed and with glazed eyes, you couldn't really follow the words.
His girl was kind of submissive to him (in a non-bdsm sense) and not terribly bright really, so she'd just listen while he read in this exultant style...I think he was somehow erotic in the way he took in and chewed the texts.


rhubarb:
Rhubarb used to be a major fetish with some people here, notably cariad and Uncle Ed (who have left now, unfortunately). Useful for all kinds of sex purposes: tickling a pussy, spanking and many other things.
