This was a very good answer.
Some points of clarification:
Hi Im a 33m when I was a teen my older sis would dress me up. I didnt tell her I liked it but I did. When I was about 20 or so my mom caught me masturbating while wearing her things. She is OK with it she even has bought me some of my own things. But we talked about it and why I was wearing her things. Talking is the best I think. If that doesn't work, talk with a therapist. A surprising number of heterosexual men enjoy wearing women's clothing, so don't jump to any conclusions. The most important thing for the boy is knowing that Mom still loves him. If necessary, Mom should also talk to a therapist!
At that age, a boy has become interested in sex, and has very little opportunity to learn or even to ask about it. He is likely to do such things as this just to see how it makes him feel. Don't make too much of it. He is probably already embarrassed enough that he wouldn't benefit by any further punishment.
LOVE HIM ANYWAY. You don't have to "do" anything. He's not hurting anyone by dressing up and if you even ask him about it you could damage his psyche. Just leave it alone and he will either grow out of it or not. Either way, you are his parent and need to show him the love and support that every child deserves.
If your son likes to wear girls clothes then let him do so as it is his decision and there choice of style, just encorage them even if that means getting them a wardrobe of their own and if you are the only person who knows don't tell other people until your son is ready to tell
Let him know that he may not have a lot of straight friends. Cross dressing intimidates other boys and usually disgusts grown up women. Even if he is in the majority (most cross dressers do it to please a woman in their life) most heterosexual woman won't be in to it and most think that you're somehow not 100% man. The best he could hope for would be a homosexual coupling with an other cross dresser.
First, the act of sniffing panties is harmless. Many teenage boys do it though most return the panties when finished with them. Definitely deal with the stealing. Dishonesty should not be tolerated. You might consider having father talk with him. on the side, about making sure to always return them such that women in the house are not alerted to his activities. This may be controversial, but I think it's the best course given the fact that he's not likely to stop.
Here is what you do if your son wears woman clothes:
Let him do what he loves.
Love him anyway.
Talk it out with him
Take him to a thrift store and let him pick out an outfit or two let him try it on in the store and tell him when and where he can wear it.
Get him some make up, high-heels, wig, bra, panties, bra snuffers, and other female stuff purse etc... and let him put that stuff on and take him for a walk outside.
Let him wear your clothes and fake boobs through the house
haft lay down the law and encourage if not force him to stop. Do not nurture this habit that is the worst thing you can do.
Oh come on. Would you freak out if your daughter wore boyshorts? Jeans with a fly in the front? Perhaps wore a sports sweatshirt with the name of a male athlete and number on the back? Panties are just clothing. Wearing them does not magically change the boy into something different. But...and this is the possibility that you should check out unemotionally, was the boy different already before he had the desire to wear panties? Crossdressers are born, not made.
Nothing. Men in Scotland wear skirts all the time. They are called kilts. Say nothing to him and if he is making a nonverbal statement about how he sees himself it may be worth a discussion on why he wears it, but take it easy and be calm, considerate, and respectful.
Yes you should, it makes you more attractive.
You should make a list of the pros and cons, plus why you want to wear girls underwear. As a 12 year old boy, you will need to make your mom understand why you do not want to wear boys underwear.
You could tell your dad you are a transsexual or you have a gender identity disorder. However, he may get angry or send you to therapy. This may not be worth being able to wear girls underwear.
make them wear "goodnight" pull up underwear and not let them wear big girl or boy underwear until it stops
no you shouldn't make all the boys want to have sex with her.... but you should let her make her won choices in what she wants to ware. i say let her ware them if she wants to.
Not girls loo much hotter without em ugh yeah let's do it
Because most girls thinks its sweet for Boys to let girls wear their jackets
The parents should not let there child wear pants like that
No. I demand my children to wear underwear, at least when leaving the house.
Unless its for a costume, girls do not dress boys in a dress and tights. Dresses are still considered girl’s attire. Although most girls prefer to wear pants and leggings these days, they still wear dresses. Women tend to wear dresses more often than girls. Girls also wear tights. Sometimes with dresses. A boy should not put on tights. Boys do not wear dresses, so there is no reason for him to wear tights. Plus boys used to wear tights centuries ago, but tights have become feminized in the modern age, meaning girls are the ones who wear them now. Its not appropriate for boys to wear them anymore. He should stick to pants or shorts and let girls wear the tights
Don't let her wear skirts or make her wear shorts or leggings under skirts otherwise you could buy skorts(skirt with built in shorts) for her.
Then dont wear shorts.
No its is quite wiered idea and is also not a sign of normality and if you are going to wear a used underwear then it also may cause some of the allergic problems Actually more common than you think however if you are going to wear someone elses you should have the courtesy to let them be made aware of it It's just fine. Just make sure you/they wash "yourself/themselves". I myself am going to start wearing my girlfriend's. Ignore the naysayers, wear whatever you prefer. Many people will be judgmental because they are not mature enough to 'not care' and 'mind their own business'. Whatever your comfortable wearing is good for you, but as others said, wear clean ones or purchase your own.
