Can't get a date because I'm too scary-looking

You are not a monster, you are just physically intimidating. There will be women who will avoid men like you at first because they're afraid of being assaulted, but there will also be plenty of women who will be attracted to you right away because of your height and build. Remember that nearly all women desire a man who is tough on the outside and sweet on the inside. You're also wrong that most women want to dominate men, in fact the reverse is true: most women want to be feel delicate and feminine next to her man and want to be dominated by men. So if you can give off the impression of being a nice guy who can stand up for himself and make women feel protected (not scared), then you won't ever have to look back.
