How many times have I spent money and time on some woman, finally gotten her into bed, only to find she's one of those that needs "extra help" to finish, if you know what I mean. If I don't go down there and put in some extra work beyond the usual call of duty, I'll look like a selfish bastard. What gets me is that they're not all like this. With some you have an easy, mutually satisfying good time. Why hasn't natural selection eliminated these defective females?

OK, here's my proposal. Fellas, if you find a girl like this, leave some indellible mark on a very visible part, like the face or hands, maybe with somehting like that ink they use to catch bank robbers. Eventually we'll have them all labelled, and we can make informed decisions about exactly how much we want to invest.
