derectory
A booklet listing da most virile studs in da area who are both "willing" and able to "get it up" easily and reliably.
You don't need a derectory to find an eager sex-god to share your pillow... just dress in a skimpy outfit and wiggle yer ass/boobs at prospective dudes whom you meet around town, and see if said hunks get a visible hard-on.
