pierced nipple ladies!

So a friend of mine who is kinda over dramatic told me that nipple piercings gunk quite a bit and you gotta really clean the hole and push the shit out, especially before a boyfriend goes to suck on them or it'll gunk in his mouth, 
I do clean all my piercings when I shower daily, so I'd do the same for them. Is this a serious issue ? Or what? What's the truth! 
And if you'd like to add any positives or negatives too :)
