Telling a new partner that you have herpes is certainly a daunting and difficult task.  Unfortunately it's one issue that herpes carriers will have to deal with for the rest of our lives.  The good news is it gets easier the more you discuss it with others...so hurry up and deal with it already!  Plus, what's really at stake here?  A relationship with one person?  Well if that person really likes you, he/she will come to terms with your having herpes.  And if your partner can't do that, then - at the risk of sounding cliché - it's not worth your time anyway.  There are plenty of people out there who will accept your condition.  Don't be afraid to do some weeding out and find the right ones.
