I kissed someone with what i thought was a pimple but now know was a cold sore. does that automatically mean i have herpes? and will i for sure get outbreaks if i do?

Oral and genital herpes virus is spread easily by oral or genital contact with someone with an active herpes ulcer. The virus is attached to the nucleus of cells, and severe stress from any source can activate the virus, causing typical ulcers. If you begin to have episodes with ulcers, ask your physician about antivirals like acyclovir or Valtrex, which can alleviate active virus.
