I'd just like to point out one important fact here....
All these people saying "get your son tested" are all females who obviously never were a little boy in the 1st grade who had these problems. Its kind of funny how the two guys here telling you what you ought to do, who have been through this stuff personally, are the only ones telling you not to do it and rather spend more time with him yourself along with your husband and fix the actual problem.
I was under the impression only a couple people in this thread had a penis. Valkyrie is questionable, but I hope the rest have vaginas. I think we know wtf we're talking about when we say don't get him tested unless all other routes have been tried. Women telling a woman what to do with her son in regards to how young boys think/act is about as stupid as me giving a 12 year old girl advice as to which is better-the tampon or the pad?
