Are pimples on nipples normal?

Okay... so this might be odd but when my nipples are leas relaxed, they have like pimple sized bumps on them? Almost like goose skin. Theres no like white dot on them, and when my nipples are relaxed they are completely smooth!

And sometime its one nipple and not the other! They aren’t bloody or irritated. Just look like pimples but with no pus.
