text: if u have herpes simplex, is it ok 2 kiss someone else that has herpes simplex? i have a cold sore right now, and i was wondering if it would b ok if kissed my gf who also has the herpes simplex virus. to sum up what most of these people are saying, cold sores are in fact a form of herpes. there are herpes simplex-2 which is a serious vd (vanarial disease), is totally contagious when there is an outbreak, and is  treatable but not curable.  then there is herpes simplex-1 is is generally above the waste, usually marked by coldsores, not nearly as serious but still treatable but not curable.  there are treatments for either simplex-1 or 2 but remember this!!!!!! you can spread one to another, meaning a person can have a cold sore on their mouth and transfer it to someone else's genitals through oral sex...thus herpes simplex-1 (a mild problem) can turn into simplex-2 (a serious problem).
