That is right, but the problem is not often discussed by young people before marriage, although our young people of today are beginning to discuss it more and more, which is a very good thing. In some states in the United States a wife has no rights if she resists her husband. I do not know the law in India but custom compels her to submit to the sexual needs of her husband. There are no such laws here. Yes, but the custom is here.
Customs are harder to change than laws.
You are giving them advice which they cannot accept. Not if they learn the art of resistance. It boils down to education. I want women to learn the primary right of resistance. She thinks now that she has not got it.
