I met a sex worker from whom I asked only for protected oral. She opens the condom and places it on the top of my penis, when I notice that she is approaching with her lips to unroll it, then I immediately block her and with my hand I remove the condom from the penis to then put it back on myself correctly immediately after. After few minutes of intercourse I finish the encounter and leave. no further contact. What risks could I have run? For sure I know that the risk for HIV is 0, but all the other STI? I have a family and I absolutely cannot put anyone at risk. Thank you so much for your kind reply. 

The fact that your casual partner was beginning to unroll the condom with her mouth does not change the benefit of condom protected sex.  Same benefits.  This was a virtually no risk encounter.  I would not worry and do not see any medical reason for STI testing.

On the web you can read all kinds of things and having an accredited source like yours is very important!

If I’m not inappropriate I would ask you why you are so sure of your response, I mean, the part of the condom on which the lips rested with possible saliva, after a few seconds while I was unrolling the condom, came into contact with the mucous membranes of the penis. I would be interested in knowing technically why no transmission of viruses or bacteria can occur. Certainly I do not want to repeat what happened to me, unfortunately I am old enough to know the weakness of the human soul and if something similar were to ever happen at least I would be able to give myself a scientific explanation. Thank you so much

I should add that some commercial sex workers actually put the entire condom into their mouth to apply condoms yet we have never seen or heard of an STI acquired when condoms are applied in this way.
