I had to verify this story before I posted it here because it seems like something entirely too bizarre to be true.  Well, it's quite true.

A German couple (30-year-old wife and 36-year-old husband) who have been married for eight years and are still childless recently visited a fertility clinic in the hopes of finally having children of their own.  Much to the surprise of those staffing the clinic, the couple's interview revealed why they hadn't yet had children — they weren't having sex.

Testing indicated the husband and wife are both fertile and should have no trouble conceiving.

When asked how often they have sex, the couple had no idea what the question meant.

The clinic spokesman said, "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."
