some if it might miss and go somewhere else. It's hard to get jujuba right where your aiming sometimes.
No you shouldn't have to take them out while you sleep. They simply get irritated... Try putting bars in instead of rings.... Rings tend to move a lot more and cause irritation.
I may have responded to this on the wrong area. Switch over to bars... They move much less than rings.. Rings cause a lot of irritation. Both my nipples are done twice each. I have to wear bars or I have the same problem.
I had my left nipple peirced today. I had read posts on how much it hurt and I'm not gonna lie I was so nervous. The only part that hurt was the needle coming out and the bar going in, a quick sharp pain and it was all over. 5 hours later I had a warm bath and put salt in it, also had a egg cup with warm salty water, got a few cotton buds and wiped all the dried blood away and it is absolutely fine, don't even notice it unless I knock it. Everyone is different and everyone's body's react different to things. So from experience it's no good reading up on how much it hurts because it all depends on you and your body. Just remember to keep it clean. Salt baths are best! Good luck!!!
