I have heard something similar for myself. When I am focused I think can come off kind of intense. It can put people off. It's just one mode of mine. 

Remember

I often hear that I walk pretty "forceful", like, fast and not timid... I think it's a double-edged sword, as it helps in keeping the crazies at bay, but it also makes me look like you'd better leave me alone... 😅

I'd like to think that it's not looking attractive per se, but looking capable:

Body language is huge. I used to consider myself less than average attractiveness. Now I am confident and I know who I am and I think I am the sexiest man there is. And I can tell that others know I feel that way.
