I have a birthmark on my . Is that a turnoff to guys?

So.. i have a birthmark the size of like a nickel on my lower left cheek. Its not a mole, its just a light brown mark, but its noticable. I get insecure about it mostly when i wear bathingsuits becuase if the bottom of my bathingsuit comes up my birthmark shows. I get insecure because i am scared that if someone sees it they will think i have a piece of crap or something on my and get grossed out haha. I am a confident girl, but I just dont want to be judged because of my birthmark. So on that note I was also wondering if this birthmark I have would be a turnoff to a guy?
