Im back and it’s only been 2 weeks. I had another encounter with a csw. She does massage with happy ending or oral. Says she does not have sex in bookings. Anyway we get to the part where she is going to give me oral. The condom she uses is Adore. I’ve never heard of this brand. 

Then she puts the whole condom in her mouth before performing her party piece of putting it on my penis with her mouth including rolling it down inch by inch. 

My concern is that some of her saliva could have gotten into the inside of the condom when it was in her mouth and therefore I could theoretically contract an STI. Is this a real possibility?
