The last time my boyfriend had a cold sore was about two years ago. is there any chance of me getting herpes if we perform any type of oral sex?

HSV-1: Cold sores spread from person to person by close personal contact, such as kissing. Cold sores are caused by a herpes simplex virus (hsv-1) closely related to the one that causes genital herpes (hsv-2). Both of these herpes simplex viruses can affect your mouth or your genitals, and can be spread via oral sex. The virus can be transmitted to others even during times when you have no blisters.

No: Cold sores also called fever blisters, you don't get cold sores from fevers or colds but they can be triggered by them. The virus that causes cold sores is usually passed via a kiss, shared utensils, or other close contact. Otc creams and ointments may help discomfort and speed healing. Frequent sores may require a prescription. Cold sores are a top mouth problem.

There is a low risk: Cold sores are caused by the herpes virus. This virus also causes genital herpes. It is possible to pass the virus from oral to genital infections via oral sex. Herpes is most likely to be passed on during the prodrome (the burning or tingling that occurs just prior to an outbreak) or during an outbreak. Avoiding oral sex during these times will decrease the risk of transmission.
