I would go with sweat too. He had been sitting for an hour in polyester bottoms. Sounds like bum crack sweat to me. Again nothing to worry about.

I think sweat sounds like the most likely cause. I've had a few embarrassing moments while at my children's school plays where i've stood up after sitting on a plastic chair and noticed a small oval sweat mark on the chair 😳 it usually coincides with me wearing my polyester work trousers. I honestly don't think it's anything to worry about. I completely understand why you don't want to broach the subject with your son, especially if he is quite a private person.
