You're not the first person to use deceit to attract the opposite sex - but you know you've taken it too far and are hurting people.
Amateur psychologists hat on, I'd say:
You're trying to fill an emptiness and sense of inadequacy in your life with sex and desperately use any means to do so (I'm not judging, been there myself). Unfortunately the end result is making you feel even more inadequate - which is the predictable result.
My amateur RX would be to start addressing the inadequacies in your life one at a time instead of running for escapism. 2nd don't judge yourself by anyone's standards but your own, and let your own conscience be your guide.
Maybe your wife makes you feel inadequate also and this is a way to prove she's wrong? You should decide if that relationship would be the first thing to turn around. A second thing would be to apologize in a letter, email, or phone call to the people you've felt you hurt.
They may react angerly at first, but knowing you're sincerely sorry will make it easier for them (and you) moving forward.
The only way to fix deficiencies in your life, character, etc. is being tough and wanting to. Escapism through booze, drugs or women only makes you feel worse and more hopeless.
But as a man, there's nothing more gratifying than seeing the results of your desire and hard work coming to fruition. And from what you've posted here you've already taken the most difficult first step - and that's being honest with yourself. Good luck - start fixing things - and stop beating yourself up!
