Normal for toddler to play excessively with their privates

Funny story: I was at the house of my mom's friend and her 3 year old daughter comes waltzing out with a stuffed animal. In front of several guests she starts humpin' the thing and all her mother said was "go in your room and do that!".
Whatever...better life lesson to take to my own son than the painfully awkward sense of sexuality my mother instilled.

Why don't you relax about it - a whole lot - so that your over reaction isn't the issue, which i think it is. He's 2 - yet you've decided that HE has an issue exploring himself. Everything you've said says YOU have the issue. Lighten up.

I did as a kid and my 4 year old son did too. Still does from time to time but not nearly as often. If he is doing it at inappropriate times then correct him for that first, don't obsess about it all the time or he will do it later just to get attention. When he is older he will grow out of it.

Normal child behavior, try redirecting him when in public. At home let him be just tell him that that's something we do in private in our own room. Don't push it too much by telling him "no", it'll back fire on you and he will do it just to push your buttons. Kids like to cross bounderies. See how far you'll go before you snap. I say ignore it at home it'll pass is just a phase.

He's going to be a man - so he's just getting ready for a lifetime of touching his knob and wanking and scratching his balls, LOL!!

Honestly research the work of Sigmund Freud and stop freaking out.

maybe he can sense that it annoys you and keeps doing it for that reason..

If he's old enough to learn the word "no" then you can start teaching him about "public behavior"

but the act itself is natural.

yes its normal, the medical term is "exploring himself"

thats like my brother when he was little its just a kid thing i guess

Of course. If you look up the psychosexual stages of development by Freud it will explain a lot of what stages your kid will go through. He's probably just in process of discovering what's down there.

Its normal for kids to do it but you might want to have a word with someone if hes doing it all the time, you can't tell them off but you need to let him know that doing it all time time isn't right.

I have a 2 year old girl who seems rather interested in hers, too. I guess since they're in diapers 98% of the time, it's really unexplored territory down there for them and they go all out.

It's normal for children to explore their bodies and since your son is two years old he might continue doing that until an older age. You might want to talk to him about doing it at the wrong places and when he can do it.
