Friday afternoon public service announcement...

Safe sex is a good thing. I am not one to care how we get it on... as long as we can get it on. Well, there are some interesting ideas on how to make this happen out there.

5. Spray-on protection

Since his teens, Jan Vinzenz Krause struggled to find a condom that fit correctly. He thought the pursuit of the perfect prophylactic was hopeless -- until he went to the carwash.

Inspired by the spray-on soap and wax, the German Krause developed a spray-on latex condom, which he claims always fits perfectly and feels natural.

However, many men find the design off-putting; the spray-on condom comes in a hard phallic case.

Men slide themselves into the cylinder and layer on the latex, providing full coverage.

The Jolly Joe, as Krause dubbed it, frightened many men during the testing phase -- they only put the case on their fingers. (Spray on gloves anyone?)

Others felt the loud hissing wasn't sexy and the latex takes too long to dry -- three minutes.

Krause explains to Time, "It needs to be ready in five to ten seconds." So for now, Krause is waiting for a quicker-drying latex.

Uh, yeah three minutes is a bit too long Mr. Krause. But keep trying hard...
