Herpes is a sexually transmitted disease, so unless you have sex with someone who has it, I don't think you need to worry. Having herpes and knowing how much it freaks people out has led me to just not tell others that don't need to know. It can't even live on a towel, so if I had an outbreak and dried off with a towel and you used it, you would NOT get herpes. In general, it is unsanitary to share razors and other objects that draw blood like toothbrushes etc. Not because of std's though.
