Trying to draw a quantifiable link between penis size and the male psyche is a complicated endeavor, which is why scientific research is scant. But Trojan, manufacturer of Magnum-brand condoms, has been filling in the gaps—conducting studies to determine the psychology of its ostensibly more gifted clientele. "They claim to be very spontaneous and very assertive," says Trojan's vice president of marketing, Jim Daniels. But Daniels divulges a potentially devastating secret: The Magnum isn't any larger than Trojan's other condoms. Its comfortable fit is due to an innovative "baseball bat" shape. The length and circumference are identical to those of other lines. Only the XL variety is larger—by 30 percent—and that's only required by about 6 percent of the male population. "You've got the image of the package—it's premium; it's gold foil," Daniels says. "And what guy doesn't want to think that he can handle a Magnum condom? There's a certain machismo involved."
