There was a study looking for virus in semen done years ago in people who were HSV 2 positive. It was rarely found.
The likelihood that this person happened to have a lesion inside the urethra and then ejaculated and there was enough virus present to drip into your anus or vagina is just so very unlikely.
You were concerned that you couldn’t post and I was going to fix it but I see this now. it is all cleared up?
