Sex strange chats
In Giacomo Casanova’s memoirs, written in the late 18th century, he takes credit for inventing a primitive version of the cervical cap, when he describes using partly squeezed lemon halves during sex.(A painting of the Italian writer also exists where he appears to be blowing into a condom-like prophylactic, but researchers believe that Casanova’s covers were for protection from venereal disease, not pregnancy.) Condoms turned another technological corner in the year 1844, when American manufacturing engineer Charles Goodyear patented the vulcanization of rubber, which he had invented five years earlier.(Just silly.) In 10th-century Persia, women were told to jump backwards seven or nine times after intercourse to dislodge any sperm, as those were believed to be magical numbers.
And other methods seem, by today’s standards, straight-up bizarre.(Possible side effects: sterility, brain damage, kidney failure and death.) In the year 200, the Greek gynecologist Soranus advised women to abstain from sex during menstruation, which he mistakenly believed to be their most fertile time of month.
