Lol, I used to get so irated with Micle Jackson when in every dace he included the genatal thing. Of course me being a Christian this was absurb. But he said in the moment he did not realize where his hands were half the time. When one of my nephews (NT) was your sons age or there bouts he did the same thing when he was excited. My sister just let it go. He grew out of it. He to did not know what was happening in the moment. Yes, it is not desirable, but you and I know your son has no sexaual intentions behind it. There is nothing sexual about it, the hands just need something to grab and boys have a convienient built in nob. Lol

My son also does this. Itsone of his stims. All in all i dont care what others think about it. If its not harming him tell people to back off. Ask them what they do that no one knows about. Or if u have a stim( we all do) and your excited do something too. But if its inapproprate like down the pants or anything that can cause harm i would redirect like with the sensory toys....

My son used to do that and I'm sorry to say it took a long time for him to stop. We always reminded him but he continued to do it for over a year. He has grown out of it, so be patient and keep reminding him.

ok, no advice, but I was just talking to my partner who teaches college basic math skills and she has an adult student on the spectrum this quarter who does this while he takes tests... I hope your son can get past this!

I've told my son that he only needs to do that in the privacy of his own room or bathroom and that even though it's not a bad thing now people don't wanna see him doing that when he gets older so it's better to try to find another way of showing his happiness like running or jumping. I've even gone so far as redirecting his attention to something that makes him think like therapy. Bottom line if it's causing problems or becoming a habit break it now in the beginning don't wait til it in his subconscious.
