5 Things You Didn't Know About Condoms

Think you know all about the protective rubber? Well, think again. Here are five things you didn't know about condoms.

1- Condoms have appeared in cave paintings
In Johnny Come Lately: A Short History of the Condom, author Jeannette Parisot claims the appearance of condoms in cave paintings are estimated to be 15,000 years old. Although Parisot notes that the condom is being used during sexual intercourse, that doesn't signify the condition for which the man was wearing the condom. This is another matter altogether, since the man in the cave painting could have been brandishing the condom for one of three reasons: some sort of ritual, as protection against pregnancy or as protection against an STD.

All three are reasonable possibilities. There is no cause to think that the clever minds behind cave paintings hadn't also discovered some connection between the sexual act and one of any number of outcomes, including pregnancy or a stretch of days featuring extremely painful urination.

5- Invisible condoms may be next
For all those folks forced to use leather, silk, velvet or rubber as thick as an inner tube, the invisible condom could only be a pipe dream. In this case, "invisible" actually means a gel that hardens according to increased temperatures.

Clinical trials on the invisible condom have been carried out by Quebec’s Laval University, in conjunction with the Canadian Institutes of Health Research and the Centre Hospitalier de l'Universite Laval.

It is one of a number of products being developed which falls into the category of a female condom, some of which have received government approval. The Invisible Condom, however, is still awaiting approval.

Bet you didn't know those! :P
