Look. You have society... The life of civilized human beings that you excel in. You make good money and in this jungle that we live in, that makes you a good hunter. Which will in turn make you a good provider for your mate. You are ahead of most males because of your education and ability to think. That would make you the alpha among civilized men.
Then, there is nature. The society which you do not excel in. Women are ruled by emotions and their lack of chemistry for you makes you not as desirable as other males in their world. We are still animals and have basic instincts. Good genes are what makes attractive people attractive. In nature, the strong will survive. The strong and fast are the good hunters and women will look for this in their mate.
So to answer your question about society viewing men who sleep with a lot of women as being "the man," you have to look at it from mother nature's standpoint. In nature, sewing your wild oats is what makes a man a man, and it ensures that the good genes will be passed on through time. It is just life. Natural selection.
But we as men are blessed with the power of our minds. We can solve complex problems and build great feats of architecture. I personally believe that human mental power is stronger than we think. Your thoughts can manifest themselves through the power of will and perseverance. So, there is still hope for you on your journey to becoming the alpha. You have already conquered one world. Just go back to the basics and remember that strength is a a character of good genes. From there, confidence and a little charm will do you very well. Good luck!
