Many people (read: men) find condoms icky: the texture, the lube, the fact that they're on your penis… there are plenty of reasons for them to give your willy the willies. But they serve an important function, and if you refuse to wear one you're basically an a-hole. Besides, it could be way worse. You could be trying to get laid in the nineteenth century.

To prove this point, some brave research bloggers from io9 decided to make a condom the old-fashioned way, using a recipe from a book published in 1844. The result, which was made from part of a sheep's digestive system treated with lye and sulfur, was understandably disgusting, and not something modern people would want to put on or in their bodies (except for Charlie Sheen).
