Hello.
You need accurate information about STDs, etc.
I suggest you read the information in the STD Expert Forum at:

Any virus can enter your body through the bloodstream--even the tiniest tear in your cuticle can give access to your body. So when you're exposing yourself to bodily fluids, you should always use risk reduction. Fingers can be protected by using latex and spermicide. I suggest you get tested for STDs to put your mind at ease. Dr. J
