Today starts National Condom Week, just in time for that holiday with the pink hearts and cupids.  In order to celebrate, here is a fun condom fact for you from Wikipedia:

The first uncontested description of condom use was written by Gabriele Falloppio in the 16th century, in response to the earliest documented appearance of syphilis in Europe during a 1490s outbreak. Falloppio described linen sheaths soaked in a chemical solution and allowed to dry before use. The sheaths were sized to cover the glans, and held on with a ribbon. Falloppio claimed that experimental trials of the sheaths demonstrated protection against syphilis.
