I used to take some offense at the idea of women "training" their men. It sounds so degrading, like teaching a pet a new trick. It puts the woman in charge and the man in a subservient role, and it's not truly enjoyable for either person. It's not a partnership at that point, but more of a matriarchal dictatorship. Neither side is supposed to be "in charge" of a healthy relationship.
However, I do recognise that many men grow up with terrible domestic habits. We leave wet towels on the floor, we don't cook or clean or tidy up, things like that. These are habits and behaviours that we should have grown out of, but if a boy has his mother picking up after him all of his life, it won't even occur to him that towels should go anywhere else. Why would it? Don't count on self-awareness and consideration developing naturally. We do need to be told things sometimes. If you pick up after a man and wait for the guilt to set in after self-reflection, you'll never get what you want. If you ramp-up the consequences of inconsiderate actions ("Put his wet towels under his pillow!") then you will grow to see your man as a child. I think the better move is to talk about it. It's still training, in a way, but respectful.
