With the "next-generation condom" initiative, Bill Gates is acknowledging that the practical reasons people don't use condoms warrant honest conversation.
As the late author Norman Mailer put it, "The only thing you can depend on with condoms is that they will take 20 to 50 percent off your f***." In a conversation with Madonna on the topic, Mailer also condemned condoms for making people part of "the social machinery" and destroying "most of the joy of entrance." Madonna argued that condoms are "essential in the age of AIDS," but conceded, "they feel terrible."
If we're honest, many of us do see condoms as robbing us of pleasure, stealing some excitement and spontaneity from intimacy, and dulling the intensity of sexuality. It's okay to say that. These factors are the primary reasons that still only 60 percent of teenagers claim to use condoms. These factors warrant acknowledging. From there, condom usage declines as people grow older. The number one reason we have seen given time and again for refusal to wear condoms is the reduction of pleasure.
