Win free condoms.

Want to be a condom tester and share your findings with the world? You may want to hop a plane to Brazil, where the non-profit group DKT International is hosting its fourth condom tester contest. Participants head to a DKT website where they note where they used the group's low-priced, Prudence brand condoms and share their experiences with the product. The 100 best consumer stories will receive free condoms for a year.

DKT hopes nontraditional marketing efforts like the condom tester program will help counter cultural stigmas against using contraception.

“Contraception is more controversial than sex,” says Phil Harvey, founder and president of DKT International.

Those participating in the contest haven't shied away from sharing some racy details, but if you want to read them, you'll need to brush up on your Portugese or use a translation tool. Find the site here.

So far, more than 3,000 stories have been submitted from Brazil as well as other countries. With the help of the program, DKT has sold more than one billion condoms in Brazil.

DKT markets and sells low-cost condoms in low-income countries with the help of donations from private organizations.

“Using bright colors, fresh and sensual imagery is one way the product appeals to the consumer, making its use positive and fun,” said Chris Purdy, Executive Vice President of DKT International.

The group reports on the condom tester program this week at the International AIDS Conference in Washington, D.C., which it co-hosted with several other not-for-profit groups. Learn more about the conference here.
