18 year old black male here. I'm a freshman at my school, which has a pretty high white population. This is no problem, my families white and I know how to interact with white girls. However, the girls at my school are more conservative when it comes to dating or hooking up non whites (their not racists, to clarify.) Despite this, I get the occasional eyes from a white girl when I'm walking to class or getting food. I'm 6'4 225, and black untop of that, combined with a stoic demeanor. I've tried approaching women before and they always have a look of slight reluctance in their eyes, but I can usually get them to see I'm not as aggressive as I look.

The thing is, I hate having to spend the first few minutes assuring this poor little 5'3 girl I'm not gonna kidnap her; but I know my demanor and serious manner is what contributes heavily to my own attractiveness, so I don't want to have to keep using beta tactics to approach women. My question is, are there any specific tactics I can use to make my approaching of women in public areas more natural as to make them less intimidated without seeming like a bitch?
