I know i will sound controversial but here goes;

That drama is so common in most households,its like a common cold. I wish there is way we can prepare our children for the future cause its changing.
Men and women are going to be equal in all things even Sexual freedom.
No one gender is going to enjoy the monopoly of having multiple partners.
Right now the way we are socialized does not prepare us for the future that is happening.
Men we are taught to keep quite with their feelings and not engage in verbal arguments. They mostly solve their problems with fists.
women are taught how to express themselves and abstain from any physical expression i.e sexual fulfillment tendencies.
so what happens. man cannot win a verbal argument with a woman resulting to fists.
Women hide their desire to express their sexual freedom resulting to frustration; and anger when the man cheats.
Point is women cheat, alot even in marriages just like men, the problem comes in when the man starts slipping in what she held to be her ideal e.g working, fit, etc Then she will start walking to the man she has hidden for so long or towards her fantasy. Then all hell breaks loose.
The biggest obstacle is the social cultural norms and traditions that hold us back, add a good dose of religion and we have sexually frustrated people in our society.
