Whenever I use a condom I have a hard time keeping it from slipping off. Is there anything I can do?—R.Z., Pittsburgh, Pennsylvania

Answer:

For health and liability reasons, most condoms are longer than most guys—that is, standard condoms are seven inches, while standard guys are between five and six. The idea is that it's better to have too much protection than not enough. The problem is that the typical guy ends up with an inch of latex rolled up at the base of his penis. Besides being uncomfortable, this makes the condom more prone to unroll or catch inside his partner. That inspired Adam Glickman, founder of Condomania.com, to introduce custom-fit condoms. Download, or request by phone (800-926-6366), a "fit kit"—two paper rulers to measure the length and girth of your erection. With that info you can select the best fit from 55 sizes. A 12-pack is $12. "We've sold every size, but it's trending toward narrower and longer," Glickman says. "That makes sense, since the early adopters are guys who are the most unhappy with one size fits all." While the company expects to have one of the more interesting databases out there—hundreds of thousands of penile measurements—Glickman says customers need not worry about their personal data being shared with anyone.
