Welcome to the forum.
This was an entirely risk-free event with respect to any and all STDs. Kissing of course carries risks of colds, influenza, etc -- but no STDs are transmitted by kissing, or by oral contact with skin near the genital area. Even with overt oral contact with the vaginal area, the oral partner almost never catches anything. You needn't worry at all, do not need testing, and if you have a regular partner, you can safely continue sex without transmitting anything.
And whatever my mouth touched it was dry.
I should add if there was contact it was brief.
