My boyfriend and I are great about protection. Even though I'm on the pill and we've both been tested, we still use a condom every time. Lately, however, they all seem to keep breaking. We've broken three in the last two weeks. We're very good about putting them on properly, leaving room at the tip, etc. The ones that have broken have not all been from the same box (but they have all been the same brand). The condoms never break when we are in missionary, but whenever we try to change it up is when they break. Does anyone know why this could be/have any suggestions?
