I don't like kissing much...
I think the dangers of casual kissing are quite known (or was it just because I did a paper on STDs in high school??)
You could always do the Julia Roberts thing.. (from Pretty Woman, and just not kiss..
)
It is
much better to know the person well and know their health condition/s too..
I got ginigivitis, not sure if from kissing or a white filling gone wrong, or my Dad-?? (Many people have gingivitis anyway, and where I live eating from one common salad bowl is the norm in families.. so..?)
If you are worried about kissing, also make sure to eat from own plate and not from the same bowls or drink from the same glasses/bottles..
I was sort of ridiculed for not eating with the same spoon as a friend (I knew of her health problems! /sigh/) and my Dad thinks my insisting to use my own toothbrush odd-?? /rolls eyes/
People just have different standards sometimes... (or like to mess with you..) In China, people still spit on the floor .. on buses even!!
In a way, we are often surrounded by germs and it's important to have a healthy immune system, so it may be more productive to work on that... And just be selective in kissing partner/s..
