@Sleeper: This sounds like the personalized version of Woody Allen's orgasmatron.
Can you think of an appropriate Woody Allen quote? The one that comes to my mind is sadly not relevant to thsi conversation, but it always makes me laugh: "I don't want to achieve immortality through my work... I want to achieve it through not dying."
@BrainiacV: Are you thinking of Larry Niven's Known Space series...
I bet Brainiac I, II, III, and IV would have got this -- only one of the best science fiction tales of all time -- "Steel Beach" by John Varley.
It also has one of the most attention-getting opening lines of any sci-fi book:
"In five years, the penis will be obsolete," said the salesman."
Here's another interesting quote I just found on the web:
"Some Krogan believe that testicle transplants can improve their virility, counteract the genophage. It doesn't work, but that doesn't stop them from buying. Ten thousand credits each, that makes forty thousand for a full set... Someone's making a killing out there..." — Garrus, Mass Effect
@Crusty: With regard to the title of this column, I feat that if you mentioned these undergarments to Mrs Crusty, the "warm tingle" you felt would not be caused by your underwear (although it could be coming from the same general vicinity :-)
