1. If I am getting a good seal, as evidenced by running my finger along the edge and the strong suction felt when I remove it, would changing the type of fold I use possibly fix the leakage?
2. If I still have too much leakage, should I go up to the larger size? I am over 30, not terribly sexually active right now, have never had kids, and use the small size duck for exams, so I bought the smaller one.
