This natural latex product is not the same ingredient that goes into paint. What goes into paint are synthetic polymers that look just like natural latex but have a completely different chemical makeup and different properties than latex rubber. So if a customer announces that they have an allergy to latex, you can answer with confidence that there is none of THAT kind of latex in your paint.
Kissing with a tongue ring is an erotic, exciting experience for both parties. Even though your first thought may be to grab your girlfriend and let the extra sensitive kiss explode between the two of you, there is a waiting period you must observe to allow your tongue to fully heal.
It is best to keep ice on your tongue as much as possible the first few days. Do not eat spicy food for the first two weeks. You are suppose to keep the longer piercing ring in for 10-14 days time depending on when the swelling goes down. Your tongue will be swollen for a few days to two weeks. If they do not give you a rinse, then you should buy some kind of sea salt solution and rinse with that. You could use Listerine but it is not recommended for the most part not right away. After about two weeks time you can change it to a smaller barbell. I would use a metal bar but acrylic balls. Acrylic balls are less likly to crack your teeth and wear down your enamel. Best way to change your tongue ring is to take the first one out, and replace it with a clean new one.
