Is this normal?

[Elvalight]

Eh, this is kinda awkward -_- For a while now my nipples have been, um, doing their own thing. Like, I know it's normal if you get cold, but for months they've been doing it. I'll be anywhere, alone or in public, and suddenly they'll just harden for no reason. They're also a lot more sensitive than they used to be.
I mean, I haven't bought a better fitting bra yet, but it hasn't caused this before.
Is this because of puberty or is it normal?

Well i think its normal and its becuase of the hormones and that yo uar in th e puberty and your body change :) thats my opinion :) my nipples do that sometimes too

[shaune]

[vickilynn]

This is normal. Mine are mostly hard now.

My nipples are the same, wether l'm wearing a bra or not, they get hard for no reason....

[ChrisTJ]

Yeah mine are the same, normally it is when I get a little cold but they do it randomly sometimes too. Thankfully I don't think anyone has ever noticed.

I sometimes get it randomly. Mostly when it's cold though.
It's all normals - don't worry :)

[Michelle_Stilt]

Ya, I have the same thing actually. My right one is always harder.

You're normal. Usually that comes with cold but sometimes they can be more sensitive to friction than usual
