I have found that some ASD children tend to be more sexually active when they are growing. Children should not be made to feel bad or punished for this. I would simply explain that he should do this when he is by himself in his room. I would also be careful of what he sees on TV and hears on the radio. This is very normal. My son went through this and is still going through it. He is 15 now. I feel that they simply do not know how to use self control as well as others. I would also start talking to him about Good touch, Bad Touch. This will not only give him a insight not to let anyone touch him but to not touch anyone either. Also, Children as young as the age of 3 years start masterbating. They could be doing it and not even realize it while watching TV or even talking to you. They are just figuring out their bodies. You child should be just fine. If you are worried though, Seek a therapist advise.

I think you should be concerned. It may be just a childhood phase. I agree with everyone that sexual behaviors are very common and typical in children 3-6 but they are mostly playing with themselves or looking maybe touching others. But if it is a reoccurring issue, the behaviors happen more than once, frequently, after being told no, or interfers with daily functioning then you need more people helping on figuring this out. Especially because he is getting other children involved it is a very slippery slope. Is your child verbal? There are psychologist and programs that work with children as young as 4 in relation to sexualized behaviors. Overall though they do occur because it feels good, often it is finding appropriate replacements and a lot of supervision and black/white rules. Sorry you are going through this! I hope it is just a childhood phase, but better safe than sorry.

Children are curios. I know that many children are curious. I would definitely let him know that touching someone else is inappropriate. I would also let him know that he needs to wash his hands on a regular basis. I would think about behavioral therapy for him. I would get a therapist that has experience in working with children with this disability so that they can do it in a way your child understands without making him feel bad. Most of all I would let him know you still love him no matter what.

Sticking his finger up his butt, having his baby sister grab and pull his wee wee. Always having his hand down his underwear, plays with himself while going poop, putting his fingers in another little girl. And he also downloaded porn type apps on th kids kindle.

We have experienced something like that. It's weird. We learned one thing you can do is answer questions. Or have a male authority figure, that you trust with this kind of thing, very matter of factly ask him questions. Making it a big deal isn't helpful.
