My DH seems to (not often but definitely regularly) have a wet patch on his trousers which is presumably urine that has leaked out after going to the loo? Is this normal? I mention it occasionally if I see him and it's on his suit and he usually just fobs it off or laughs. I've just now seen another bloke his age in a suit with the same thing. Is this a thing?! Should i be buying some sort of pad?
