I have a very red sore near my lip but have never had any sexual activity. Can I still get a cold sore without having sex?

Yes. Herpes Simplex type I commonly causes sores around the mouth and lips. HSV 1 is transmitted through oral secretions sharing objects like utensils cups, kissing.
YES YES YES. The herpes virus on the LIPS is completely different from the one spread by sex. They are close "relatives" but quite different! Hope this helps Dr Z.
