intimidating?

I've been told I'm intimidating, I'm a 17 year old 4'10" highschool senior who has only ever had 1 boyfriend and often worries about how I'm percieved. Aparently, I'm an intimidating person. I intimidate people so much aparently they don't want to flirt with me ever 😓 I've been told as much often, my body has very broad shoulders and a broad chest. I've always been super self conscious off my shoulders. Is it ok to be a short, intimidating (cuz that makes sense) girl with football player shoulders? I'm starting to doubt. What exercises could I do or clothes could I wear to decrease/hide my shoulders? How can I be less "intimidating"?
