If I gave my boyfriend oral sex with a coldsore, then had unprotected sex afterwards. Is it highly possible for me to now have genital herpes? Thankyo

Herpes. Yes, very possible. Most likely type one, since there is two types. If you get a cold sore, follow up with a ob/gyn.
Herpes. You are mixing up two viruses. First, the facts. Once you have a herpes infection you cannot get it again. It does not move or migrate to a different part of your body. Herpes type one (once called 'oral' herpes) is found in 75% of humans in the western world. Genital herpes or "type two" is a different virus and a different infection. 25% of humans in our world have this infection.
