hey man, im knew here but i just read your thread and wanted to add that im the same!
I find watching reality shows has been a MASSIVE help in learning body language, like, you wouldnt just go out into the field and just start oggling every pair of legs that walks on by trying to analyze, people will be like "wtf??" (thats if your green and stand out like a sore thumb right?)
I find shows like Dating in the dark, the bachelor and bachelorette, jeremy kyle etc are really good. It's amazing that after a while of just trying to look out for little details and piecing them together your soon able to natuarally just look at someone and have a fair sense of empathy etc.
I've just started out doing some field tests in the past few weeks and i DEF think that im able to notice more and pick up on a lot more things, not only in a shorter amount of time, but im able to respond and in most cases get a really positive result
Im still pretty green though, havent been doing it for long enough BUT i interact with every girl whos body language i read as open and suggestive and ive never been turned away or made a fool of.. give me another month of field testing and see where im at.
