Can you get genital herpes from a cold sore?
— Mary Lou*

The simple answer is yes — it is definitely possible to contract genital herpes from oral sex.

Genital herpes is caused by the herpes simplex virus (HSV). There are two types of herpes viruses — HSV-1 and HSV-2. Genital herpes is usually caused by HSV-2; oral herpes (cold sores) is usually caused by HSV-1. However, genital herpes can occasionally also be caused by HSV-1. Someone with HSV-1 can transmit the virus through oral contact with another person's genitals, anus, or mouth, even if they don't have sores that are visible at the time.

Other than abstinence (not having sex) the best way to prevent herpes is to use a condom during any type of sex (oral, vaginal, or anal). You should have your partner use a dental dam every time you receive oral sex to protect against STDs.
