You really seem to have a warped sense of reality about STDs, considering all the posting that you have done over a simple kiss.
Oral herpes (HSV--1) can be transmitted through kissing, but the risk of transmission is really low, less than 1%. And there is probably at least a 50% chance that you already have HSV-1 anyway. Same with your family members. Many people who have HSV-1 have had it since childhood and don't know it.
More importantly, oral herpes is not a 'malignant' infection- the worst it will do is produce a simple cold sore. You can't "hurt" anybody by passing it. And you can't catch/transmit it through casual contact (sharing chopsticks, food, etc.).
If you need more information, read the thread from the expert forum below, or search it for similar threads. Since oral herpes is not even a STD anyway, this forum is not the appropriate place for discussion.
