Transmission of genital through ?

I've been looking at several websites, and most seem to say that is spread through skin-to-skin contact. I read that you shouldn't touch an affected area to reduce the risk of spreading the outbreak to other parts of your body. I also read that both genital and oral can be caused by either HSV-1 or HSV-2. So now I want to know if you can get genital by performing oral ? It seems clear that you could get it by receiving if the person has a cold sore on his or her mouth, but what about the other way around? Can you get genital if nothing has actually come into contact with your genital area?
