Is it easy to get herpes?
If you have sex with someone who has it, is it a definite that you will get it? How likely?

The odds are irrelevent. You either get it or you don't. The odds are higher (maybe over 50%?) if they are having an outbreak and lower if they aren't. If you are exposed to the virus, it has to find a way to enter into your skin and get in your blood. It can usually find a way in through tiny cuts in the skin you can't see.

This brings up a good question.

Can Type 2 enter into the blood stream anywhere on the body and infect the person? That seems logical to me; however, most everything that I've read indicates that there has to be genital to genital contact.

Colin,
In that case, everything you've read is completely WRONG. You can catch and transfer HSV2 anywhere on the body.
