Not much to say other than research suggests risk is very very low but not zero. Risk goes up if you have any open sores or cuts in your mouth (and, of course, she actually has to be HIV+ and not on PEP drug treatment). Some docs suggest you not floss or brush teeth within an hour before oral sex, as even brushing can create micro-tears on your gums. Within a short time those tears would heal. If you have good oral/gum health here's little to worry about. Using mouthwash after oral sex is always a good idea. Nobody likes being around a dude with cum-breath  

I only wanted to add this as a notice because you are hoping for some "stability" right now while planning to travel in the near future, and I would love myself to see that "stability" as well (we all want that), but in addition to the visa getting reduced soon (or at least that's what they say everyday for a couple of months now already), the "stability" seems a little uncertain, still.

I think if you are able to show that you have an issue with returning due to the Airline unable to fly then you will be given dispensation to rebook or reschedule. This was the case back in March when the conflict started.

Keep in mind another factor, as we speak: The total duration of our stay is also at risk (if you are expecting to stay 55-60 days and then they reduce the visa eventually to 30 days as they keep saying on the news).

So, it looks as though there is some stability with travel in and out of The Middle East. We are seeing some very attractive deals from the likes of Emirates, Quatar, and Etihad as the companies try to entice us back to using them? Would you be confident to take them up on this? Certainly, you will unlikely be covered by Travel Insurance in the event of being stranded, trust me I was victim of this! Alongside the threat of conflict is now the added concern of possible aviation fuel shortages. It's a difficult situation to balance as some deals do look attractive, personally, I will be sticking with flying direct to LOS for the immediate future.
