Background: 6'4", 230 pounds, 15%BF, long brown hair just below my shoulders, built physique (not super jacked), short beard (I shave using 5 mm razor). 21 years old. I also do boxing.

My parents tell me that I look like I'm about to punch someone when I walk, but I'm bulk and that's just normally how I walk. I don't have an angry look (atleast I don't THINK)

Today I go into the deli and one of the girls who works there starts chatting me up out of no where and after talking for a bit she says "wow, you're soo nice I thought you hated me" and "you're the person I'd go to to protect me in a fight". blah blah blah. I wasn't very interested especially since I go there a lot to eat. But it got me thinking, she thought I hated her and looked mean until she talked to me. I got to thinking that I could be scaring the shit out of girls so they might be avoiding me. I also just got out of the gym, so I'm wearing a tank top and basketball shorts.

I don't want to scare people, but I also bulked up as a defense mechanism from bullies since I had a long history of being bullied. It also got me thinking that girls automatically assume I don't like them if I don't approach and talk to them (this could be big for guys who question cold approaches). Truth is, I'm not a big meanie who wants to fight everyone. I just want to protect myself. Any advice?
