A related discussion,
6yo son naked wrestling was started.
I don't know if your two sons watch wrestling or not, but there is a wrestler who -- as gross as it may be -- forces his opponent's face into his butt... with his clothes on, of course. But, if your boys have seen this wrestling "move", I would not be surprised if that is where your 7 yo son got the idea. I would not be too worried though, I work with boys of that age, and they do a lot of strange things out of curiosity or imitation. If they do watch wrestling, I would curtail it!
Thank you for all of the information! I truly appreciate any help and/or advise given!
THANK YOU!
Of course when you discover such behavior you are going to be upset - that is a normal parental reaction. And it may well be that your son is being truthful when he tells you he does not know how it happened to occur to him to do this. You asked sensible questions. Now it is important to set a clear, unambiguous limit on this behavior, which I imagine you have already done. Let them both know that this behavior is out of line and that it is not to be repeated. For your younger son, tell him not to cooperate with such requests, whether the request comes from his brother or anyone else. Talk with them about personal privacy as it relates to certain parts of their bodies, buttocks and genitals, and that this privact applies to other people as well.
