What are the changes of catching herpes for a male receiving oral sex over boxers?

[IDunno123456789]

Hi, I am a male and I received oral sex from a female over my cotton boxer shorts for about 2-3 minutes at most. The boxers before she put it in her mouth were already really wet with pre cum and after I pulled her off I saw her drop a lot of spit on my boxers which was covering and hugging my penis, she also advised me she got it wet my boxers while it was in her mouth. After 4 days of the encounter she told me she has a tingling sensation on her lips which the next day turned into possibly a Herpes break out on her upper lip. If she does have herpes what are my chances in numbers (0, 1 in a...) and in words (negligible, highly unlikely, likely or fairly likely) that I also caught herpes from her spit which possibly could have went through my boxers. Lets say I never had or have any form of herpes. Is the consider amount of spit able to mix with the pre cum already on the boxers and slide to my growing or thighs and get me infected? Please if you can answer in numbers and words it will be great. Also two weeks after the encounter now I had a flare up of hemorrhoids this occurred only after my bowel movement and after checking looks just like my hemorrhoids and are getting better. Or could the spit have traveled down from the boxers to the thighs slid down to my anal area and caused something there. Please I am really over worrying about it :(

Zero risk. There are no variables in your story including the spit that has you at any risk. Zero risk so you can move forward without concern

Hi Feeling thank you so much for your response you have me at east. Is it because the virus would not be able to survive the journey? Also are you a health professional in this area?
