Contraception fail? Apparently, 45 percent of men report some sort of bad experience with ill fitting rubbers. Researchers from the Kinsey Institute surveyed 436 men who had used a condom while engaging in vaginal sex sometime in the last three months. Almost half complained of rubbers that didn't fit; those respondents were also more than twice as likely to report breakage, slippage and an overall lack of pleasure.

Is this a case of size? Are male penises getting larger? Or smaller?
