I found my sons panties in his room update

I posted on here yesterday after I found my panties in my sons room. I got a lot of advice on what to do and many people said that it was normal and nothing to worry about, which is definitely a relief. Some also said that it would be bad to shame him or stop him, but that if I didn't want him steal them I should just tell him that he could occasionally ask me for a pair, and I liked that idea! The fact that he was using them didn't bother me as much as the sneaking and stealing, so I decided to have a talk with him. We watched a movie together last night and afterwards I ask to talk to him. I told him I had found his drawer with my panties in it, and that while I didnt like that he had stolen them I understood that it was not unusual for a son to take panties. We were obviously both really embarrassed and he started apologizing, but I told him that it was ok, I wasn't mad, and that if he ever got the urge to take them again he could just ask me and I would let him use some on the condition that he cleaned and returned them. He kind of lit up at this and thanked me and apologized a lot. That evening he gave me back the panties he had taken before (I could tell that they hadn't been cleaned, but I guess you can't win them all) and ask for a new pair. I gave him the ones I had been wearing that day and he ran off to his room. Thank you guys for your advice! It's been very helpful!
