I've just come from Boots, where I purchased exactly two items: dental floss, and lubricant. I was astonished to discover that the cheapest dental floss available at Boots (their own "Smile" brand) cost MORE than the Boots brand lube.
Let me say that again: dental floss is more expensive than sex lube. Thus, lube is more accessible to the general populace.
Could this be why Britain has the highest teen pregnancy rate and worst oral hygeine in western Europe? I think we need to re-evaluate our cultural priorities.
