Am I the only ones that think teens shouldn't pleasure themselves?

YES.

Refer to post below titled "My Boy".

Masterbation is the way for teenagers to become accustomed to how their bodies work. This is preparation for sex and procreation. It also allows teens to become emotionally ready for sex - this is ESSENTIAL for stable relationships in the future.

As for stains on clothing - have you ever heard of "wet dreams" subconcious ejaculation whilst sleeping - he probably isn't doing anything - he may be wearing underwear to stop his PJs getting stained.

By the way, the word is not "thing", it is Penis.

In case you wonder whether I am correct or not, I am a childcare professional with extensive experience.

Agree with Honehe 100% Leave your poor son alone. If he is masturbating in private then don't worry. If he is doing it in public explain that there is a time and place. As Honehe said it could be wet dreams over which he will have no control.

Don't humiliate or embarass him, it will only damage your relationship and he is bound to hate you. I can't understand why people get so prudish and uptight about this topic as it is normal behaviour. Relax.

This is completely normal for his age. Even though I must say it's a shocker. I caught my son "doing it" and I just walked out and later apologized for walking in his room without knocking. Of course I told him that this was totally normal but I would prefer if he did it when no one was around. There is not much more you can do. I did buy some books from Amazon that I gave to him and I also read.

Hi I have to say I totally agree with these replies, positive dealing is far more productive than negative. You need to be approachable in all instances when children are at this age and if you put the shutters up now you will never get them back down again. He is probably having wet dreams and may well be very embarassed, his friends may not be at the same maturity level as he is and so he not be able to even talk to them about it, don't make him even more insecure. I have three boys and although they are not in their teens quite often when we are watching tv at home my ten year old will have his hand down his pants and he doesn't even realise he is doing anything he just is. We ignore him or have a very light hearted joke with him which he joins in with us even though he will have a flush of embarassment he will still talk to us because it's OK. Also as one lady commented it's not a thing it is part of the body and use whatever word is best for you all, in our house it's a winky but the boys chose that not us, but because they chose it they are not bothered about speaking about 'winkies' and the strange things they tend to do.

Masturabation is suposed to releive sexual tension. If a young boy can pleasure himself it can help him control his temper better and stop him from going after any girls. Of cource it doesn't stop boys from wanting sex but it helps them to refrane. It also helps to avoid unwanted or uncalled for erections that could imbarass the boy. Masturabtion isn't just something boys do either, it shares the same benefits for young women as well.
