Originally it was the length of the furrow in one acre of a ploughed field. An acre is an area that is one furlong long and one chain wide. For this reason, the furlong was once also called an acre's length. Around the year 1300, England standardised the furlong as 40 rods or 660 feet.
Vanilla sex is what a culture regards as standard or conventional sexual behaviour. Different cultures, subcultures and individuals have different ideas about what constitutes this type of sex. Often, it is interpreted as sex which does not involve such elements as BDSM, kink, or fetish activities.
By analogy, the term vanilla is sometimes used as a synonym for plain. Although vanilla is a prized flavoring agent on its own, it is also used to enhance the flavor of other substances, to which its own flavor is often complementary, such as chocolate, custard, caramel, coffee, cakes, and others.anilla flavoring in food may be achieved by adding vanilla extract or by cooking vanilla pods in the liquid preparation. A stronger aroma may be attained if the pods are split in two, exposing more of a pod's surface area to the liquid.
