If you and your wife have never had any other sexual partners (no oral, anal, or vaginal sex) it is unlikely that you could transmit any sexually transmissible infections to one another.
The only exception is herpes. Many people get herpes on their mouths (cold sores) early in life from non-sexual kissing with relatives. It's possible to spread that from the mouth to the genitals during oral sex later in life.
I think you are being over cautious, cut loose you guys have each other and that's an awesome connection to have. Most people could only wish they were virgins for each other.
