Well, no one is qualified to diagnose you. However, it doesn't sound like you have PTSD. PTSD comes from trauma and I am not seeing any trauma discussed in anything you wrote.

It sounds like you have developed a bit of an anxiety issue. In my opinion it sounds like you were striving for some kind of perfection and there is really no way to ever be perfect and it must have been boring after a while playing that game constantly with so many women. It doesn't sound like you could ever really be relaxed and just be "you" and actually develop a relationship based on that. What's the point in having so many women anyway, nothing was actually "real" because it was just some kind of mind game you were playing all the time. It sounds like you actually forgot to just be "you" and now when you are around women the game becomes the focus and you don't want that anymore and you feel lost now. You were constantly playing some kind of Politically Correct dating game and lost yourself in the process.
