Hi, since a condom was used with the vaginal none of your symptoms are related to that act so that leaves us to the unproteced oral and the risk for contracting any std would be close to zero. Topical irritations that your describing from oral could be fungal related but not std related. Since the swab test came back negative its very possible your making them appear by constant touching, checking and pulling and could be anxiety related. Maybe best to see a dermatologist at this point.
