There is nothing you can do post exposure to prevent an STD.
HIV is no risk
Syphilis is low risk in develped countries, lower risk in woman and with no sore it is no risk.
Gonorrhea would be very low risk.
Percentage...can't really put a definate number to it but less then .01%.
No need for testing. Combined with your low risk and the amount of time you did it, it's not worth worrying about.
Only symptom to look for really is a sore on your lip, but if you get sores then you really have no worries.
I got that .01% number out of the air. I had a situation similar to yours months and months ago and I went through and found out how many people had gonorrhea in my area then cut that in 1/2 for men and woman. Then I figured out the total population and got the percentage. It was something like .00001% that I could have gotten it. So just to help you I gave you a number but in reality it is going to be lower then .01% like mine was. The risk for all practical purposes is zero.
