Guy don't like me because I'm scary....

I never had a boyfriend even through high school. I've always liked guys but they never liked me back or talked to me. I didn't really have many friends at all. I was asking my best friend (he's a guy) why guys don't like me and he said it's because I intimate them and scare them. Wtf does that mean? He said since he's known me so long he knows how I am and I'm great, but others find me scary. I asked if that meant ugly and he says "You're not ugly. You're pretty. Beautiful actually. Just scary". So says I don't have a resting bitch face. I have a resting Sargeant face. That I look like I'm about to yell at someone to give me 20 whenever I walk in the room. He also said my combat boots don't help and I'm heavy footed so I stomp when I walk and when you hear loud stomping and see a 6'3 girl with a resting Sargeant face it can be pretty scary. Then also how I dress. I dress in very dark clothes and this boy says I have "The look". I asked what the look is and he goes "Pretend you're a teacher to 7th graders and they are all yelling and not listening. You say nothing. Just give them "The look" and it's dead silent". That has me thinking that maybe its not that people don't like me because I've always felt like people around me just hated me, but I guess they're scared of me. I asked how I can be less scary and he said he likes me just the way I am. But I don't want to be scary. I have been told by my mom I'm a little intimidating but I didn't think people were actually afraid of me. How can I be less scary?
