My boyfriends has herpes, what worries me is that he wants to have oral sex with me and I'm worried that he;ll infect this area too. Is that possible?

Herpes. The overwhelming probability is that you are already infected with this virus and therefore it is unlikely that his going down on you is going to cause further problems. But if you want to be absolutely certain and you do not yet have the virus then don't let him give you oral sex. Enjoy.
