Yeah, they know. Most girls look in the mirror everyday. I used to have a 'stache but I plucked it out with tweezers and it hasn't came back. It was the most painful thing I've ever done to my face(try it). &YES, I'm persian too :) so if you meet some hot persian girl, know that she had a stache & unibrow at one point in her life, if she denies it she's lying.. her [most likely] rich parents paid for the electrolysis or pay/paid for her to get it waxed.. and it is REALLY embarassing, and I got picked on but problem solved. Guys gave me shit about it but it was when I believed they had cooties so them saying things didn't bother me as much as girls, because girls can be fucking cruel.
I knew this mexican girl who, in highschool, would tell people I looked like a dyke for a haircut I had. She had the hairiest arms I'd ever seen in my life. Looooong ass dark black hairs too but I never said a word to her, I already knew people talked about it. I hate girls.
