Condom slipped and exposed small cut on penis during sex with CSW

I had vaginal sex with a CSW in Thailand around 44 hours ago.
I had a small 'cut' on my penis shaft. It was a little smaller than a match tip. I got that the day before from friction during masturbation. It had started healing and had scabbed over before the sex. The fluid was never bloody and in fact you could not notice it.
During the sex I used a condom. Part way through the sex, I applied water based lube on the condom (wasn't required to begin with as the vagina was wet) and continued the sex. After 2-3 minutes I pulled out and noticed the condom had slipped. I have no idea if the 'slip' was due to the pulling out or had happened while performing the sex? Anyway, the 'cut' was exposed.
My obvious question is the chance of exposure due to the above?
Would it be enough to warrant PEPs?
Also would the lube in anyway act as a kind of barrier or even a vassal for the virus to attach itself through the break in the skin?

I asked the woman if she had had a HIV test? She said she has one each year along with other tests (not necessarily STDs) on the blood and body, and that she was -ve. She did say she was probably due for a test.

Any help would be grateful.

Sorry this post was missed.

If the head of your penis was still covered then you had no risk. The cut would not put you had risk. Neither PEP nor testing would be necessary is such a situation. Hope this helps.
