I keep telling everyone this, but I really don’t think I say it enough. Go slow. Way slow. I waited a year after I got mine done and it took me a year and a half to get to a 4g(5mm) on one side and a 0g(8mm) on the other. I say go slower than me. I learned most of what i know not to do by messing up/ experimenting since there is no real guide for stretching nipple piercings. And because my 8mm kinda ripped a little… >.>
Also, like I mentioned earlier, insertion tapers are worth the extra money (i never suggest dead stretching or taping because of the risks & massive irritation). They make the stretch so much easier.
Be sure to us lubrication on the taper. If you stretch when taking a shower unscented soap will work. It may sting a bit and you’ll have to rinse it well afterward. I used jojoba oil and it worked well.
Make sure you have good fitting jewelry as well. If the wearable is too small your nips will try and eat the jewelry. I usually suggest using jewelry that is 1/16” to 1/8” longer than the initial piercing jewelry to accomodate swelling and so you can see if you blew out. Which is possible when stretching any piercing.
When actively stretching I tell people to use straight barbells. Single flare plugs made for lobes almost always will have to short of a wearable and the flare can embed a little into the surrounding tissue (I had this issue as well). I never suggest double flared jewelry either. It will get stuck and will be a pain to get out. CBR’s and circular barbells are ok at smaller sizes, but at about 6g and larger they tend to be a bit heavy..

I believe I’ve covered the basics. But I’m answering this from my iPhone so it is a little hard to do. If you have any questions feel free to ask. :)

:) thanks. If you do stretch it, go way slow & don’t use cheap tapers. I actually ended up ripping my left nip a bit because of that.. Insertion tapers are worth the extra money. Trust me.

At one time my left was at 0g (8mm) but I have since taken it back down to a 14g. It almost split one night when I was drinking (before i was edge). My right, I’ve been a bit more patient with and it is at 4g (5mm). I’m only going to a 2g on it.

For about the last year I’ve been leaning more towards “hardcore” modifications and most of the stuff I initially wanted to do had already been done by one of my friends. I felt that it would feel like I was copying him if I went for the things I wanted that he had; tongue splitting, labret scalpelling, subdermal horns (even though his are transdermal), and a few other things. One day while I was scrolling through my dash, I saw a photo of some stretched nipple piercings and I though it was totally rad and wanted them. So I did it. =]

There were no complications with the stretching process, but it is a little awkward when I am out in public. I like wearing tight shirts and they poke out a lot. I do entertain requests to show them when people ask and am nice about it. Like when people ask me about my lobes. They are just uneducated and want to know.

There is nothing really different between a standard nipple piercing and a stretched one except the diameter of the jewelry. I’d expect breastfeeding to be about the same unless it is stretched big (like more than 5mm). The only problem I see with it would be reinsertion of jewelry and leakage. Larger than normal nipple piercings tend to have to be tapered back in if they are out for a while (I have to taper in my 4g if it is out for more than a half hour..). I’ve heard of regular (14g) ones leaking, so I would think a large diameter piercing might leak more or have more of a chance of leakage.
I’m not fully sure on all of this though. There aren’t really many sources for this topic so I had to assume some of it from looking at articles about normal nipple piercings and breastfeeding.

It does remain and the stretch can be quite pleasurable. My nipples are at different sizes (0g & 4g) and both are still about the same sensitivity. Though every person & piercing is different so it may very well lose or gain some. 

Any of my followers have some input? I can only cite my own experiences at this time.
