Welcome to our Forum. I'll be pleased to comment and complement you for your commitment to safe sex. Despite what you may have seen on the internet (always a bad idea- while I am sure that nearly all who post on the internet mean no harm, statements there are often taken out of context, are misinterpretations or sometimes are just wrong) or from the doctor you spoke with (who was wrong), all of the activities you describe represent safe sex and as long as your condom was intact. And if your condom looked intact, it was - when condoms break, they break wide open. There are no STIs other than perhaps transmission of herpes type1 the cold sore virus that can be transmitted through kissing including French kissing. Those who maintain that such transmission is "theoretically" possible need to put their theoretical statement into perspective - the likelihood of getting an STI is just as theoretically likely as your likelihood of being struck by a meteor falling from space.
With these general statements, let me address your specific questions:
1. If she had hiv (because obviously we don't know) based on the exposure I had, what is the likely hood I have contracted it?
Zero. Most commercial sex workers do not have HIV (or other STIs). They tend to do a better job of avoiding risks and getting checked on a regular basis than many others who engage in casual sex. more importantly however, condom protected sex is safe sex and not STI, including HIV is transmitted by kissing of any sort.
2. Could I really have contracted it through French kissing? My dental is pretty good and I hadn't had any sores that I was aware of other than maybe some chapped lips.
See above, this is incorrect. There are no proven instances in which HIV has been spread by kissing of any sort, by receipt of unprotected oral sex from an infected person, or by cunnilingus. There are a few instances (very few) in which persons performing fellatio on an infected partner appear to have acquired HIV.
3. Do you recommend testing for this incident or am I safe to just move on with my life?
I see no need for worry and no need for testing. I urge you to move on without concern.
4. If I was going to experience ars would I most likely have done so by now being about 26 days post exposure?
Yes, you would have
I hope these comments are helpful. In the spirit of providing as much information as is reasonable, I have made some comments that had little to do with the event you described- please don't them cause you to overthink things or worry- the exposure you described did not put you at risk for HIV or other STIs.
