Breast feeding help!

I want anf hope I can breastfeed my twin babies when they come but I was wondering if any one has an opinion or an idea or any experience with breastfeeding with nipple peircings? I have both of mine done and I have heard just as much good and bad so I'm pretty confused ... should I take them out now and let them heal or is it fine to leave them in and take them out during feedings? And wondering if I did the second option would they close up during feedings? Of course I want what is best for my babies.
