While potty training my b/g twins I would frequently remind my son to push his penis down when sitting on the potty. One day, his sister decided to also remind him and, um, help him. "J, don't forget to push your penis down" As she went to do it for him, I caught her just in time and gently explained that was only for him to do. Luckily, she listened and no longer tries to help in that way ;-)
