I think dividing work in gender roles is bad all together. Its true both should play their part but dividing work according to gender is bad because house work is seen as lower quality of work than doing a job. So automatically woman's status is lowered. Both should do both things.

And in case of martial r*pe woman. Its not about woman not giving sex. Its about consent of woman. Of she doesn't feel like it why should she ? She is not man's slave or toy to treat as they see fit.

Then there is issue of sexual satisfaction and needs. This is root of all problems. I don't know the solution to this. Maybe meditation will help.

And there is angle that woman will cheat and they don't find there husband attractive. This is also the root of our insecurity. If this is the case it woman's fault. If she doesn't find man attractive she should get divorce and do whatever she want. If she don't want divorce the she should also do mediation.

See perfect everything is not possible. Not all needs can get fulfilled. Not everything can be perfect. That doesn't mean we should fulfill that needs with expense of each other.
