The Provider Man:

The Provider Man is an ultra smart alpha male who is always in control of his finances and emotions. You will hardly find him in a bad financial state (this doesn't always mean he would be rich, just never short of cash) or in a emotional state. But these sexy qualities come at a price. You got to be a slave to his demands. If not he is going to dump you, doesn't matter if you are pregnant with his child. Lily Allen's guy dumped her right on the next day she had a miscarriage, so you can guess what type he belonged to. See if you can find his photos on the Net.
The Provider male works hard for his money, gives unbeatable competition to others around him and likes to play hard as well. So don't be surprised if he asks you to fellat him, or worse still do the doggy-style with you. You don't give in, the leather belt is always at his reach. Good luck.
The Provider Man is everywhere, the more visible, smart, tall, muscular, hit-with-women guys are all these type.
As long as you are submissive to him he will never fall short of providing money or other material pleasures to you.

Pros: Boy-toy, 5 credit cards, machismo
Cons: Demanding, sex hungry, doesn't value true love.

The Thinker Man:

The Thinker Man is the kind of man that most ordinary women don't like. If you are a run of the mill ordinary chick he's not for you. But if you have a woman, a woman inside you then keep reading this article. The Thinker guy lives in a Man's world, a world that you cannot even possibly imagine. Due to his imagination powers he's a highly creative guy. He loves doing impossible things, talks about thinks impossible and is easily bored. Its just a hand trick for him to write a piece of software or fix a big problem but he can't even properly arrange his clothes in the cupboard. He doesn't watch much TV, may be sports only and may be StarTrek.
He gets quite emotional at times, unusually for a man.
If he's a good guy he probably loves you with all his heart but still forgets your birthday, because there was an important project in the office. He will try to makeup by buying nice things and loving you 'with words' but each times fails to read your mind.
He thinks. And when he thinks, you better not touch him or  talk to him or stay within 10 feet of him. He talks about super computers and spaceships to you. He talks about a new world. But finds difficult to beat competition and never gives up.
All great men in this world are this type. From Nelson Mandela to Jimmy Wales to Albert Einstein. They live in a Man's World,  a world alien to you.
Where to find? It may be difficult to find and chat up with these type of guys in a pub or party since most lead an isolated and geek type of life. They do this because they have learned to face ignores from women they had wanted early in their lives. The Internet may sometimes be the only place to catch them.

Pros: They are very romantic. They will love and touch the bottom of your heart. If you respond well they do amazing things for you. Things that show eternal love. But you got to respond in words, if you don't they can't read your mind.

Cons: Finances in a mess, house in a mess, bathroom complete war zone. May not always like to socialize with your circle of friends.
