Why scared?: You don't say what prompted your query. CBC's don't check for STIs, need specific tests, like HSV, HIV, syphilis, gonorrhea, chlyamdia. If you think there's a reason to be concerned, see your GP.

Why scared?: Hi. From what you've told us, you had sex with other people in the remote past, and tested negative for STDs since then. If you've only had sex with your wife since then, what is scaring you? We don't know what you were tested for, so it's possible you could have something still that was not tested for. If your wife's had sex with other people, that could be a source for a new infection.
