I Just Want To Know If You Have Smoked Meth

I just want to know if you have smoked meth and it's been a week and I have a sore on my lip it looks kind of like a cold sore but it's kind of inside my mouth and it's been very sore I have been in gargling with Racine and salt water and my question is because of this sore in my mouth will it spread if I were to have interaction with my boyfriend because right now my boyfriend won't kiss me or have any type of contact with me other than hugging me because he thinks if he kisses me or he has sex with me that I'm going to give him herpes or something
