For all you guys complaining about not being able to pick up poly women, here is a pretty good tip, and I am sure the girls would agree.
Stop complaining about not being able to find women. Right up there with lack of confidence is when men complain about other men getting more action then them. You do realize you are immediately subjugating yourself to them? At least thats my take on it.
As for POF...not sure, I have 0 luck picking up girls on dating sites. Then again, I haven't tried very hard. I assume it works, most of my single friends use it to pick up when they don't feel like bar hopping haha.
