Lets say you are standing with the guitar hanging from you on a strap. Lets say the guitar neck is like a hand on a clock, with the guitar straight up being 12:00 and pointed at the gound 6:00. Try the neck at 1:00 moving your hand around. If that does not work, move to 2:00 and try, then 3:00 etc..
F and open Bm are often the last chords learned to play at will.
Baby steps, one finger at a time.
Sometimes learning to play a open E with you middle finger, ring and pinky first can help. You will still have to twist things around to get our first finger to cover the B and E strings.
