I have a cold, just a simple common cold. My boyfriend kissed me even after I told him he would get sick, well he didnt get sick but now he has a cold sore. Did I cause that? Its kind of concerning me, cause I dont want him to get anymore from well kissing me.
Hello. I just read through your question. Typically, cold sores are caused by viruses that lay dormant in the body, sometimes even for years. If he got a cold sore, it is most likely because he has been exposed to cold sore viruses in the past, and not because he kissed you.
