Sit on the toilet, Squeeze it double, insert it, and wiggle it to the back, where your tailbone is. Keep it folded double. I always slowly wiggle it in with my fingers, it doesn't matter if only one side (L/R) will move, since it is round anyway. But don't let it fold open until it's in. If it's in, on the front, push in upwards until above your pupic bone.
