bisexual dating' and forget that the other person has a right to know, as soon as possible and has feelings to be considered. If the relationship is strong and the person feels they can handle the exposure (or perhaps they even have experience or have been exposed to an STD) they be receptive to hearing you out and the possibility of engaging further in the relationship.
However, remember they may choose not to continue the relationship and this IS NOT A DIRECT REFLECTION OF YOU. You MUST KNOW THIS: The basis of any relationship begins with SELF LOVE. That means if you love yourself in lieu of dealing with, having and living with herpes, then you will attract that kind of love from someone like minded, regardless if they have an STD or not and the possibilities are limitless.
In the same breath you have to give others the space to love themselves and sometimes that won't include you. Just be safe, honest and truthful to yourself and above all LOVE YOUR SELF.
