Feeling insecure

Hi so im 19 and i don't have kids or anything and somehow i don't have perky titties.... Is this normal? Does anyone else have this?

I mean it's not like I'm taking my clothes off for anyone but still, they don't really seem to hang where they're supposed to. And they're really not even that big so I'm confused.

Yea it sounds silly but ughhh anyone else relate?
