Biggest mistake I see big guys making with women is talking to them face on acting hard. Instead of talking to her facing her chest I always try to get to the side. Then Usually a few sentences into the conversation I will pretend like I didn't hear her and lean my ear in trying to get eye level with her to reinforce that positive, friendly body language. You need to realize that your not that 185 lb guy anymore and have to make a conscious effort with this or your going to intimidate alot of fucking women
