my grandsons penis is always getting big and when we were teaching him potty training we told himit meant he had to potty. but now when it gets erect it is getting painful and it happens all the time. his teacher has noticed it also she says he goes to the restroom and he'llcome out and say my penis is big he will touch it and run back to the restroom and go again. we r worried should we call the doctor or is this normal?View Thread
