Hi,
Cold sore can give oral and genital herpes to your partner. So herpes from your mouth can be transmitted to your partner's mouth and genital area by kissing and by oral-genital sex.
You can have blood test and it shows if you have herpes and also they may be able to tell you which type herpes you have.
