No the numbers are not an indication of how contagious you are or any indication of an imminent outbreak. Most people are infected with hsv1, so with those partners your hsv1 infection won't matter. I would encourage you to disclose your hsv1 status with anyone before performing oral sex on them. Some may disagree with me, but I feel if the shoe were on the other foot and you were hsv1 negative, you would definitely want to know whether your oral partner was hsv1 positive and then make any decision with complete knowledge.
