Don't get this confused with the ENDUST, whatever you do.

I saw an ad for these and thought it was a joke, but apparently not!  A German sexual-health educator first announced his invention in 2006 and has since been trying to get the perfect product to market.  

He invented spray on condoms for men, a custom-fitting male contraceptive using liquid latex and some materials from a hardware store.  The prototype consisted of a tube with nozzles that spray liquid latex from many directions, kind of like a car wash.  The product evolved to self enclosed spray can. A man is to place his penis inside the tube and it starts spraying.  The problem seems to be the length of the subjected penis and the length of time it takes to dry.  That, and many men seem to be hesitant to use it!  Nothing like waiting for paint to dry to kill the moment.

You can imagine the fodder this has caused. Check out this Funny or Die video on the subject!
