Search Results: not being able to have sex

I just finished watching the documentary http://www.imdb.com/title/tt3686998/ , and I am wondering who started the battle of the sexes and how can we STOP this battle? I have been thinking about this for days and it is driving me nuts.

Men feel that they are just being "used" for money, and that all women want is money from them and that women are worthless gold diggers. The more men feel this way, the more men treat women this way. They think that women see them as worthless, and just using them. That women can't wait until they die so they can run off with their money. These men will soon divorce or dump women and go their own way.

Women think that men are just using women for sex, and to be able to have children for them. Then afterwards, take care of their children and clean their house, cook for them and buy their clothes/groceries for them. Women see themselves as useful but they need praise from the men for the things they have done, and since men don't praise them and just "expect" them to do these things as if it's their JOB and not the men's to help with the kids or the household chores, women start feeling neglected, and misunderstood and they feel men undervalue them. These women will soon make more than their men, and dump/divorce their men and go their own way.

what do you think men and women contribute or don't contribute and why? What are the reasons for the battle of the sexes and who is most to blame? Men or women? and how do we solve this to make peace?
