To keep a man happy, you must first and foremost realize that you are not alike. The way your brain process things and even your chemical make up is different. Once you accept these differences you can then start to understand your man. This is very important. If you try to make him think like you, you will fail.
A man needs to be admired. What they need is to know above all they are a great husband/boyfriend or excellent father. That there is no other man that could possibly compare to them. If you have had sex previous to them, they need to know they are better. It may sound simple, but they need a constant reassurance of this. Their egos are precious and need to be nurtured daily.
They are also very insecure. This goes with their egos needing reassurance. If you can make them feel admired, you can help to control their insecurities. Men are a lot like Toddlers. They are very self-centered and need to be pampered. If you turn your back on them they will take it personal. They have their toys and they are proud of them. If you are overbearing they will struggle for independence.
They are also more affectionate than women give them credit for. They are just raised differently, to almost suppress the need to be touched. This again goes back to being admired. They need love notes and mushy things as much as women, but they will never ask for them. By doing the little things you keep them secure, they know you are always thinking of them.
With women as a minority struggling to be equal to a man, this is very intimidating. If you can be his equal, and do as he does, why do you need him? He needs to be needed, and women are constantly proving they have their own two feet to stand on. It is okay to play damsel in distress sometimes. Do little things, like you need his help opening a jar, as simple as it may be to you, he feels strong.
Men are also visual creatures. There strongest sense is sight. This is how their brains interpret likes and dislikes. You can call them shallow, but men like to look at their women. You will find their standards are not even close to that of a woman critiquing another woman. They do not see that your butt is big, but they do see your butt. They like to see it. They like for you to want to look good, so that other men can admire them for the beautiful woman on their arm. Are you noticing a trend yet? Next time you are having sex, look at your man, I will guarantee his eyes are open and the lights are on.
If you have taken the time to read this in it's entirety than you want to please your man. Whether married with ids or single and on the prowl, if you take nothing else from what I have given to you, admire him. Tell him, I admire you. Be prepared to answer why, but it can be for the littlest thing. Then see how much he tries to please you in return.
