TIL I learned 18th century condoms were a common thing [1]:

> The condom market grew rapidly, however. 18th-century condoms were available in a variety of qualities and sizes, made from either linen treated with chemicals, or "skin" (bladder or intestine softened by treatment with sulphur and lye). They were sold at pubs, barbershops, chemist shops, open-air markets, and at the theater throughout Europe and Russia. The first recorded inspection of condom quality is found in the memoirs of Giacomo Casanova (which cover his life until 1774): to test for holes, he would often blow them up before use.

Or not? Interesting contradiction here. They basically used the same thing they used for sausage casing so why was it so expensive?

> Up to the 19th century, condoms were generally used only by the middle and upper classes. Perhaps more importantly, condoms were unaffordable for many: for a typical prostitute, a single condom might cost several months' pay.
