How can I have herpes 1 and my 3 year parnter always use condoms not. Was tested last year and was neg but this year positive. His results negative?

Herpes 1. Unlike herpes 2, herpes 1 is generally not considered an std. It is a common infection with about 70-90% of the world being positive by antibody testing. Herpes 1 can be acquired through casual contact. It can be transmitted sexually as well if someone with oral cold sores performs oral sex.
