I don't want to get swatted for posting the whole article, but here are some tidbits...
"A German couple who went to a fertility clinic after eight years of marriage have found out why they are still childless - they weren't having sex."
"Doctors subjected them to a series of examinations and found they were both apparently fertile, and should have had no trouble conceiving.
"A clinic spokesman said: "When we asked them how often they had had sex, they looked blank, and said: "What do you mean?"."
"We are not talking retarded people here, but a couple who were brought up in a religious environment who were simply unaware, after eight years of marriage, of the physical requirements necessary to procreate."
