Alright so Im 21 years old but my body is literally the shape of someone who hasn't hit puberty yet. For context, I'm 5'8 and thin. I weight like 100, and my boobs are small and lastly I have a rectangle shape. I recently got a boyfriend and we've been chatting so and so, I wanna seem sexy and send pics to him but every angle I take just upsets me. I have an eating disorder and im trying tk gain but im just awful at it. how do i look sexy without immediately seeing myself as underveloped and gross? I hate that I look less of a woman.
