Ok I was rearranging and tidying my sons room while he is at his fathers. I was changing his bedside cabinet for a smaller one and in doing so I was sorting and tidying his underwear and socks. I saw a sock that was dirty (the sole) so took it out to throw in the pile of washing, as thought he had shoved it in by mistake. This is where it gets weird, I found a thong inside the sock that's not mine and looks like he was wanted into it!! Ds is 14 and the only other woman it could belong to is his dads wife. I'm now petrified that he's going to be a weirdo or that there is something mentally wrong with him, my anxiety is through the roof and I don't know what to do about it, I don't know what I'm looking for by posting this maybe some reassurance or an explanation as to why he would I dunno ,please help me out
