I'm not quite sure about the definition of PUA, but in my mind that's someone who is calculated, thinking of tactics, is in his head pulling out phrases... sort of a person. Being Natural is completely different. I usually don't even talk and get them to bed... with dancing, touch, eye contact, electrified connection... I wouldn't call that PUA.
The good that Pick-up did to me, is make me realize where lies the problem. But didn't help me much in resolving it (there's one fantastic program that I found out recently though, but kind of too late because I fixed it already). And it was
then that I switched from PUA to seducer/natural.
So, first the inner switch happened, and by that I mean removing fears, pride, neediness, being in the moment, having unconditioned happiness, learning what true love is etc etc and becoming decent human being... and after that women simply got drawn to me and all fell into place.
They can feel if the guy got some inner issues so it's really hard to fake it. Self absorption is an issue and I doubt it's considered sexy.
So PUA = fake.
Natural = real.
