Sometimes it can be, Dr. Berman says. "A large percentage of people put them on backward, don't leave air on the tip and then it breaks," she says. "The number one reason that condoms break is because they are not put on correctly."
Dr. Berman says that if you're thinking about buying your child condoms, don't just leave them in his room. "Talk to them about how condoms work. Talk to them about correct use of condoms," she says. "Show them on a banana how to roll one on correctly."
