Shoulderblade would be cool but then you wouldn't be able to get anything on your back without it being silly. So maybe upper arm. Or maybe the inside of your upper arm. Or rib cage. All easy to hide too.
Everyone has their own opinion on what is "attractive", and i also think everyone in attractive in their very own way. Sure everyone will have a trending "theme" in what they find attractive, mines probably height. But that's just the rules of dating. Also, who gives a fuck what anyone else thinks? Having confidence in yourself is a lot more attractive then being self conscious, sure everyone is self conscious in someway, i know i am. But i still don't give a fuck what people think. For example, right now, across the room (i'm at uni right now) is a girl who is a lot skinnier then me, and prettier and she keeps on glancing at me with a disgusted look on her face, probably because i have bed hair, bags under my eyes and i'm sitting here in a kick-ass t shirt which is far too big for me. From what i've over heard she's a rich little bitch too. Daddy owns a massive farm, her grandparents are paying for her accommodation for this year. Do i give a shit what she thinks of me? Hell no. Why the fuck should i?
