are we talking about blowjob without condom or sex without condom?What about the PZC for porn actresses? Some want to see a negative test, which means you're fine. I heard from Thalia Mint that she has Herpes type 1 (cold sores).
I know of a porn star April Maxima that ask for test. Then you can have sex without condom but unfortunatelly you have to make a video with her for her to sell the content.
