bikini pic..opinions???

r🌹
So pretty much all my teenage years (I'm now 18), I've been called skinny ass and been told some rude things like I need to eat more cause I look like a 12 year old cause of how small I am, but it's just my metabolism. My boyfriend always tells me I look fine, he sounds sincere though but idk if he just wants to make me feel better and doesnt really mean what he says..so I need your opinions and please be honest😬
