The Internet retailer is offering a new line of condoms in 55 sizes. Condomania's Adam Glickman says the "TheyFit" brand condoms are more comfortable and less likely to tear than other styles.

But just what size would a customer need? TheyFit offers a special measuring tool on the Internet.

But potential customers don't have to worry about being labeled petite or extra small. The measurements are defined by random number and letter combinations, like "J33" or "G22."

"TheyFit" condoms cost about $12 for a dozen.
