my adult son is also unaware and unbothered by his BO and other odors. Underwear issues I got under control at about age 14. He finally saw his same issue in his younger brother and recognized it about himself. lucky for me they both gained benefit from the experience and matured. But it took some hounding from mom that made me sound like Edith from All in the Family. I have figured out tricks to control the BO and shown him but he doesn't always use them. And now that he is employed I have to worry what impact it will have and when he will figure it out. For now I just tell him to shower or clean his pits. Tips I use are a bit of hand sanitizer on the pit eliminates pit odor in one swipe. Helpful for PE and sports or anytime your out and notice it but cant wash up.

How old is your son? My son is 11 and still tries to hide really dirty underwear in a pile, so I explained to him that accidents happen and when they're that dirty, he can put them right into the washing machine (if there's nothing else in there) so I know they need to be washed right away. We also are teaching him to use the washing machine so he doesn't have to feel ashamed if he has a big accident. Or, if they are too far gone, he can feel free to throw them out and let me know. It really depends on the age and stage they're at.

Absolutely nothing unfortunately .

My son does not care about how he looks or smells. He wont shower or brush his teeth and he is 18 so I don't know what to do anymore.

My son has always been good about brushing his teeth, but as he became older he had to be reminded of showers. They all react different so all I can say is maybe just keep reminding him that he is an adult now and as adults we can't be going around smelly. We did that with my son and he soon started feeling embarrassed and as soon as I ask if he needs a shower, he knows what I'm getting at and he will get up right away grab clean clothes, towel, deodorant and gets right in the shower. He also learned that if you're going to leave the house you shower first.
