To the OP, you seem to have the innate desire to be with many partners... rather than just one. These are the strategies that men are born with... to be monogamous or to stray...one or the other. Often times a more faithful man can be tempted, but with determination and self-control this can be dissuaded. You, however, are not a faithful man... not naturally. There's nothing inherently wrong with this... unless you want to be with a woman who is innately faithful.
You can undergo the counseling if you want, but they can only teach you how to deny and control your innate desires. Fundamentally you will still be a guy that is not truly monogamous.
Enjoy women and their company... but be honest and do not lead them on (this is how you can be a good man and still true to your nature). Some relationships you have will be brief and others will be quite lengthy, but you will still have the freedom to move on when the urge hits you.
Try as you might... monogamy is not for you. Do not let societal 'norms' and other factors force you to be something you inherently are not. You will hate yourself more and only hurt those around you in the long run.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
