German sex educators plan to launch a spray-on condom tailor-made for all sizes.

Jan Vinzenz Krause from the Institute for Condom Consultancy, a Singen-based practice that offers advice on condom use, told Reuters on Thursday the product aimed to help people enjoy better and safer sex lives.

"We're trying to develop the perfect condom for men that's suited to every size of penis," he said. "We're very serious."

Krause's team (spraykondom.de) is developing a type of spray can into which the man inserts his penis first. At the push of a button it is then coated in a rubber condom.

"It works by spraying on latex from nozzles on all sides," he said. "We call it the '360 degree procedure' -- once round and from top to bottom. It's a bit like a car wash."

Krause said the plan is to make the product ready for use in about five seconds. He said it would function more effectively as a contraceptive because it would fit better and not slip.

However, before the new condom can be sold in shops, the firm must ensure that the latex is evenly spread when sprayed, as well as optimise the vulcanisation process.

Krause hopes the high tech condom, which will be available in different strengths and colours, will on the market by 2008.

He said the spray can would likely cost some 20 euros (14 pounds) as a one-off purchase. The latex cartridges -- sufficient for up to 20 applications -- would cost roughly 10 euros, he said.

Krause said he had hit upon the idea when considering the difficulties some people faced using condoms, and drew inspiration from spray-on plasters now used in medicine.
