Hi Dear, I have 8 brothers and three sons. No need to make a big deal, just let him know it's normal, however, much more appropriate in the tub, when he's got some private time. As with any behavior, in public is really not the place.
Good luck. He's exploring and making it "bad" will only frustrate him. Start to explain that he has a penis and it's normal...
Hey, I am with the rest of the ladies. I have 2 boys(14 and 10) and when they were small, they did the same thing. Teach him only in appropriate places. In public is not good. My 10 year old still plays with his, even in public. Then I have to tell him that that is not the time or place. He is autistic. Good Luck!!
Sorry this is so late! I had a similar experiene with my daughter. The pediatrician checked her and she had a bladder infection causing irritation. She was treated and it stopped.
Give him cranberry juice.
If he is circumcised, you might want to check around the head area. The dissolvable stitches sometimes do not dissolve, and irritate the area around the stitch. It makes the area an itchy feeling. And some of the stitches won’t come out till he’s a teenager. That’s a very sensitive area, so the stitches work themselves in and out, instead of just outward.

You ladies are awesome!!! I have followed the ignore method and it has worked great. He no longer does it unless he has to go Pee.
Thank you so much!
