I say middle.

i would say in the middle if you get one but if you get two you could get them on the sides, but that is just me. i cant just have once lip piercing on one side it with bother me so i would have to have one on the other side or you could always get your nose, eyebrow or septum pierced.

I've had several lip piercings (Still have one but may take it out soon.)

On the side of the mouth, it's not bad.  I had a ring in mine, and it gets in the way a bit.  It's weird getting used to, but it didn't really hurt and healed really easily.    In the middle, I wouldn't recommend a ring.  A labret is further down then a lip ring, but a lip ring will get in a lot of contact with your teeth.  I used to have a labret, and it hurt even less the the side-lip, and never really got in the way. 

I took it out to get a vertical labret, which is basically a curved barbell through your lip.  (So one ball is on top, and one on the bottom of your lip.)  That one was a little unpleasant, but I like it.  It gets in the way sometimes, but doesn't come in contact at all with my teeth as it's not technically inside the mouth.    I still have it, but I'm getting sick of it getting caught on clothes all the time and I may take it out so I can find a job easier.    

I'd lean towards on the side the most, as it comes in the least amount of contact with your teeth that way.  Even the labret can rub on the inside and end up messing with your gums (especially if your piercer isn't great.)  and chipping a tooth on jewelry isn't fun. 

I've thought about taking all mine out but my nostril and getting a monroe, but I really don't want to repierce anything so I'm waiting until I'm sick of the ones I have.   

I have a labret peircing and I love it  . I'm thinking about getting snake bites as well but I'd have to wear fangs in those to go with my labret one properly. It would look good but the £50+ that it costs is not possible for me right now. I love getting peirced but I only trust one person to do them all  . The peircer is as important as the peircing that you want.

I have snake bites, I suggest them  .

I have my labret pierced.

I've had it going on 9 years now. Never got tired of it. I'd feel naked without it.

I also use to have the snake bites back in the day. One of them got infected and no matter what I did, it wouldn't go away, so I just took them both out.

and undergunfire, i love yours   
blayzn, yours is cute too   

No, there's no certain side for anything (including ears for guys, unless thee's only one). There's no unwritten rule or anything. Say you have an eyebrow pierced, I would get the opposite side of the lip done, just to even things out a bit. But other then that, it wouldn't matter at all.

I've had my septum peirced for almost 2 years now... It's kinda a hassle to always get the bugars off it.. and it looks like i'm constantly picking my nose. and It was the most painful thing I have ever experienced... ouch.

I have a cool story,but a little off topic.I wanted to know if any of you other piercing collectors thought this was just too cool.

I had my nipple pierced for about 4 years.Then I had kids,and took it out so that I could breastfeed.So I breast fed for about 5 years.A few days ago,after about a year of not breastfeeding,I was really missing having piercings(I was actually thinking about getting my lip pierced)and I thought,"I wonder if my nipple is closed up yet".So I got out a piece of jewelry and just tried,figuring there was no way it would go in after 6 YEARS.It went right in!I was totally flabergasted.Now I'm super happy.I could never have gone through the pain of it again!Owie!Does anyone else think that it's crazy that it didn't grow over in that long?I did have it stretched up to a 6.

Sorry for the major hijack,I just really found that bizarre,and wanted to share with someone who really likes piercings.Mu husband wasn't too amazed.Maybe it really is more common for that to happen,I don't know.

And,my suggestion is:
  Center of your bottom lip,but not like a labret.Going straight through your lip vertically(not your skin)and you wear a barbell where you can see the ball in between your lips and right below.My ex had his like that,except he had one on each side of his mouth,like the snakebites are.Did that make any sense?Sorry,it's ,my husband is sittin late!

Afineohilim,I used to have my septum done,and I agree with you!Worst. pain. ever.

Undergunfire,my husband is sitting next to me,and he was really excited to see your picture! :cheeky:But,you really are beautiful!And,I love your piercings and that cool tattoo!

The one going vertically through the lip is a vertical labret.  A lot of people are getting those because it has no contact with the teeth or gums.

I've had my labret done twice and my tongue, and really at this point I want to stay away from piercings that rub my teeth or gums.  I guess my tongue wasn't too bad because it really didn't touch anything in my mouth except the roof and the fleshy part under the tongue.  I took that out about 2 years ago because I felt like I was too old for it for some reason. 

Rowan you could probably get a piece of jewelery back into your nipple because it was stretched.  Everyone is different and your's probably didn't close completely shut.  Did you have to apply a lot of pressure to get it through?

I don't think there is any age.

I took mine out because I decided that I didn't want it anymore.  I had it for a couple of years and it wasn't a big deal for me to take it out.  No one told me to take it out, it didn't affect my job in anyway, I just decided that I had it for a long time and it was time to move on.  Piercings are a personal preference.  IMO no one can tell you what to have and what not to have (unless you're under 18).  Even if you have a job that says no piercings and you want one bad enough there is ways to still have the piercing and keep it hidden.
