Hello again, and thank you for getting back to me. I would say you are very lucky, your son is able to discuss these things with you. His methods, for self gratification, are a little odd, and learning the proper way to masturbate is probably a good idea. I dont think, however learning it from his mother is a good idea. If you are comfortable, there are magazines, books, and even movies, that could probably show him without trauma, from his mother doing it. As far as taping back the foreskin, that can be a very dangerous habit to get into. If he is only releasing it once a day, to shower, it can become swollen, infected, and extremely painful, and after sometime it could just get stuck there, making the symptoms worse. It could get so bad, that he would need to seek medical attention. I understand your concerns, and maybe seeing a doctor is a very good idea. He needs to learn proper sexual activities, in a calm environment. If he wants you to go with him, to the doctor, that is great, but dont push yourself into going, if he requests you dont go.
