I am 6 foot 7 and a Police Officer. To be perfectly honest, that makes a lot of people a bit nervous around me in fear of doing the wrong thing. I have a thick Aussie accent (which isn't special down here but it does do well with foreign girls) I honestly don't really think height/weight/voice does anything different in a relationship. I don't really go off of anything purely physical in any form of relationship or bond I make and not many people I know do at all. Maybe its just the area you have grown up in and the thoughts it has left in your head. If it all seems too much for you, then I would boil it down to good old Location, Location, Location :P
