My DS lost his Nintendo 3DS so I went into his bedroom today to try to help him find it. I pulled a plastic storage box off the shelf and he immediately grabbed it to try to stop me from opening it. Inside was a pair of my knickers and one of my bras. I asked him whether he had been wearing them and he said yes. I closed up the box again and told him that cross dressing was normal and nothing to be embarrassed about, and gave him a hug.
What are my next steps? I know next to nothing about cross dressing. He's clearly mortified but I think it's something that we need to talk about. I'm not comfortable with him taking my clothes to wear so I need to set that boundary. I would prefer to buy him his own things that will fit and be comfortable, and to his own taste, rather than him wear my old and well-worn undies! I think I also need to know whether he feels like he wants to wear women's clothes, or just underwear.
Has anyone else been in this situation and could offer some advice?
