Why is one of my nipples hard and the other one is soft

Okay so it's super normal for your nipples to not always be exactly the same, like one can be hard and the other soft, and that's usually nothing to worry about. Your body is just doing its thing and they can react differently to stuff.

Like, sometimes one might be more sensitive to temperature, or maybe just feeling things differently because of how your body works. It's not a sign that anything is wrong, it's just how some bodies are, and yours is unique!

Also, your hormones can literally make your nipples react all sorts of ways, and hormones are always changing, especially when you're going through puberty. So sometimes they'll be hard, sometimes soft, and sometimes one might be different from the other.
